Description

ANTENNA WITH CELLULAR AND POINT-TO-POINT COMMUNICATIONS CAPABILITY
FIELD OF THE INVENTION
The invention relates to antennas, particularly to base station antennas including radiofrequency and backhaul radiating elements.
BACKGROUND TO THE INVENTION
Cellular base station antennas generally include one or more radiofrequency radiating elements which form one or more beams in one or more frequency bands. These radiating elements communicate with mobile devices within the region covered by the base station antenna.
Signals are also transmitted to and received from the base station antenna over a backhaul link. This may be a microwave point-to-point link, in which case the microwave antenna is generally provided separately to the base station antenna. This requires separate radomes for the base station and microwave antennas, a communication link between the two antennas and separate installation of the two antennas.
It is an object of the invention to provide an antenna including both radiofrequency and backhaul radiating elements, such that both the radiofrequency and backhaul elements can be installed in a single unit and housed in a single radome, without sacrificing performance of either the radiofrequency or backhaul communications.
EXEMPLARY EMBODIMENTS
There is provided an antenna including both a cellular antenna and a point-to-point antenna. The point-to-point antenna is fixed with respect to the radome.
According to one exemplary embodiment there is provided a communications antenna including: a cellular antenna including one or more radiofrequency radiating elements for forming a radiofrequency beam having an adjustable angle; a point-to-point antenna; and a radome; the point-to-point antenna and the radome being arranged such that the spatial arrangement of the point-to-point antenna with respect to the radome is fixed.
According to another exemplary embodiment there is provided a method of installing a communications antenna in a cellular network, the communications antenna including: a cellular antenna including one or more radiofrequency radiating elements for forming a radiofrequency beam having an adjustable angle; a point-to-point antenna; and a radome; the point-to-point antenna and the radome being arranged such that the spatial arrangement of the point-to-point antenna with respect to the radome is fixed; the method including aligning the point-to-point antenna and radome with a remote antenna so as to enable a point-to-point communications link.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying drawings which are incorporated in and constitute part of the specification, illustrate embodiments of the invention and, together with the general description of the invention given above, and the detailed description of embodiments given below, serve to explain the principles of the invention.
Figure 1 is a front view of an antenna without its radome;
Figure 2 is a side view of the antenna of Figure 1 ; and
Figure 3 is a view similar to that of Figure 2, showing the antenna with the radome in place.
DESCRIPTION OF EMBODIMENTS OF THE INVENTION Figure 1 is a front view and Figure 2 is a side view of a communications antenna 1. The antenna 1 is mounted on a support 2, which is shown as a pole but could be any supporting surface such as an antenna tower, building or other suitable support.
The communications antenna 1 includes a cellular antenna including radiofrequency radiating elements 3. One or more such elements may be provided. The radiofrequency radiating elements 3 may be suitable for transmitting and/or receiving signals in a cellular communications network. In particular, the radio frequency radiating elements 3 may be suitable for use in a cellular base station antenna.
A radiofrequency feed network 4 may feed signals to and/or from the radio frequency radiating elements 3. A ground plane 5 may be situated behind the radio frequency radiating elements 3.
In use, the radiofrequency radiating elements 3 produce a radiofrequency beam which has an adjustable azimuth angle, as depicted by the arrow 6. Adjustment of the radiofrequency beam angle may be achieved by electrical or mechanical adjustment. For example, the ground plane 5 may support the radio-frequency elements 3 and be mounted at each end on a rotating mount 7 within the antenna housing 8. This allows the radio-frequency elements 3 to be rotated within the housing so as to alter the azimuth angle of the radiofrequency beam.
The antenna housing 8 may include a back wall 8a, a top wall 8b and a bottom wall 8c, as shown in Figure 2. The antenna housing 8 may be configured to receive an antenna radome 11 , as shown in Figure 3, such that the electrical components of the antenna are contained within an enclosure formed by the housing 8 and radome 11. Thus, rotation of the groundplane 5 on the mounts 7 may result in movement of the groundplane with respect to the radome.
Also, the feed network may include a number of phase shifters for adjusting the phase of signals supplied to the individual radiating elements 3. This allows adjustment of the downtilt angle of the radiofrequency antenna beam, as depicted by the arrow 9 in figure 2. Thus, adjustment of the downtilt angle may be achieved by electrical means and adjustment of the azimuth angle may be achieved by mechanical means. In general, adjustment of the azimuth and downtilt angles may be achieved by any combination of mechanical and electrical adjustment. For example, both azimuth and downtilt angles may be adjusted by electrical phase shifters.
Furthermore, arrangements for adjusting the beamwidth of the radio-frequency beam may also be provided. For example, power dividers for dividing power supplied to the various radio frequency elements 3 may be used to adjust the beamwidth.
The angle and beamwidth of the radiofrequency beam may be adjusted remotely, as discussed for example in the Applicant's US patent application publication nos. US2004/0038714A1 , entitled "Cellular antenna", and US2006/0244675A1 , entitled "A cellular antenna and systems and methods therefor". The disclosures of these documents are incorporated by reference herein.
The communications antenna 1 also includes a point-to-point antenna 10. This point-to- point antenna may be suitable for forming a backhaul communications link. The point-to- point antenna 10 may be a microwave antenna, such as a microwave dish or a planar microwave array. The point-to-point antenna 10 may be a highly directional antenna.
The point-to-point antenna 10 is fixed with respect to the antenna radome 11 (Figure 3). This means that the point-to-point antenna 10 is oriented by orienting the point-to-point antenna 10 and radome together. This fixed arrangement may be achieved by fixing both the radome and the point-to-point antenna 10 to an antenna structure, or by fixing them together directly. Thus, orientation of the point-to-point antenna 10 and radome may or may not require orientation of the entire communications antenna 1.
Having the point-to-point antenna in fixed relation to the radome simplifies the effects of the radome on the radiation used for point-to-point communication. Relative motion of the point-to-point antenna with respect to the radome is likely to have unpredictable and negative effects on the radiation pattern and return loss of the point-to-point antenna. This is important, as the point-to-point antenna 10 may operate at higher frequencies such as 18 - 23 GHz. To overcome these effects by design is challenging, especially at higher frequencies. Furthermore, the point-to-point antenna 10 may operate in a license band in which the radiation pattern must meet strict regulatory pattern envelopes. The effects of relative motion between the point-to-point antenna and the radome would then be particularly problematic.
Such relative motion between the point-to-point antenna and the radome would also require additional components and moving parts.
Figure 2 shows that the communications antenna 1 may be mounted to the support 2 using a two-part mounting arrangement 12, 13, which may be situated outside the antenna housing.
The bottom mount 13 may include a bracket 14 for mounting to the support 2; a second bracket 15 for mounting to the antenna 1; and a pivoting connection 16 joining the two brackets 14, 15.
The top mount 12 may include a bracket 18 for mounting to the support 2; a second bracket 19 for mounting to the antenna 1 ; and a two-legged connection joining the two brackets 18, 19. The two-legged connection may include a first leg 21 joined to a second leg 22 at a central pivot 23. Each leg 21 , 22 is joined to one of the brackets at a pivot 24, 25. The central pivot 23 includes a tightener (not shown) for fixing the two legs 21 , 22 at the appropriate angle.
This mounting arrangement 12, 13 allows the downtilt orientation of the antenna to be adjusted. The top mount 12 can be adjusted by altering the angle of the two legs 21, 22 while the bottom mount 13 allows the antenna to rotate around pivot 16.
Similarly, the azimuth orientation of the antenna can be adjusted either using the brackets 14, 18 mounted on the support 2 or using a further pivot.
Thus, the orientation of the antenna can be fixed in both downtilt and azimuth using the mounting arrangement 12, 13 for mounting the antenna to a support 2. The mounting arrangement may allow the antenna orientation to be adjusted after attachment to a support, or may simply allow the antenna to be fixed with a desired orientation.
As the point-to-point antenna 10 is fixed with respect to the radome, orientation of the point-to-point antenna 10 may be achieved by orienting the radome and point-to-point element together using the mounting arrangement 12, 13. This orientation will generally be performed at installation of the antenna, although changes in the network may necessitate reorientation at a later time.
Once the antenna is mounted using the mounting arrangement 12, 13, the radiofrequency beam is oriented using electrical or mechanical adjustment as described above.
Thus, in general, the antenna housing and radome may be mounted to a support using an antenna mounting arrangement. The groundplane for the radiofrequency elements may support those elements and may be mounted to the antenna housing, possibly so as to allow rotation of the groundplane within the antenna housing and radome. The point-to-point antenna may be mounted to the antenna housing and/or radome.
The cellular antenna and point-to-point antenna may both be contained within the radome 11.
The methods and antennas described above allow for easy installation of point-to-point and radiofrequency radiators in a single unit. Alignment of the point-to-point element with the radome allows the antenna to meet the strict radiation pattern requirements for point-to-point links, which are typically microwave links. In contrast, systems with an adjustable point-to-point antenna within a radome (i.e. where the orientation of the point- to-point element is not fixed with respect to the radome) are likely to suffer from unpredictable and/or negative effects on the radiation pattern and return loss of the point-to-point antenna. The Applicant's antenna allows use of a point-to-point antenna embedded in a radiofrequency antenna, without the need to address the variable effects caused by adjustment of the point-to-point antenna with respect to the radome. While the present invention has been illustrated by the description of the embodiments thereof, and while the embodiments have been described in detail, it is not the intention of the Applicant to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will readily appear to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details, representative apparatus and methods, and illustrative examples shown and described. Accordingly, departures may be made from such details without departure from the spirit or scope of the Applicant's general inventive concept.
