Definitions
- the present disclosure relates to the technical field of communication devices, and in particular to a filtering phase shifter and an antenna.
- phase shifters can change the phase distribution of each radiating unit in the array antenna, thereby changing the beam downtilt angle, to achieve beam shaping and optimized coverage of the electrically steered antenna.
- the commonly used mechanical phase shifters are divided into dielectric sliding phase shifters and transmission line sliding phase shifters.
- the dielectric substrate has a first side and a second side opposite to each other, the phase shifter is arranged on the first side, and the filter is arranged on the second side;
- each of the second microstrip transmission lines there are a plurality of second microstrip transmission lines, and an extension direction of each of the second microstrip transmission lines intersects with an extension direction of the rotating arm.
- At least one of the plurality of the second microstrip transmission lines is a slow-wave structure.
- the dielectric substrate is provided with a rotation axis hole at a position corresponding to the first microstrip transmission line, and the rotating arm is rotatably disposed in the rotation axis hole via a rotation axis.
- a central angle of the at least one fan-shaped open-circuit stub is 90°.
- At least one of the radius, the central angle, and the opening direction of the plurality of fan-shaped open stubs may be different.
- the present disclosure provides an antenna comprising the filter phase shifter described in any of the above embodiments.
- connection should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium.
- connection should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium.
- the electrically adjustable antenna uses independent filters and phase shifters. Although it can achieve frequency isolation and phase adjustment, the filters and phase shifters are designed in a separate layout, which makes the whole device larger.
- the current microstrip filter uses a straight short-circuit line as a branch line, but the straight short-circuit line
- the connection with the main transmission line is wide, which is prone to discontinuity and causes large insertion loss.
- a large spacing must be ensured, making the circuit structure not compact and the corresponding filter band not steep enough, affecting the filtering effect.
- the filter phase shifter includes: a dielectric substrate 1 , a phase shifter 2 and a filter 3 .
- the dielectric substrate 1 has a first side 11 and a second side 12 opposite to each other.
- the phase shifter 2 is arranged on the first side 11
- the filter 3 is arranged on the second side 12 .
- the dielectric substrate 1 is used to provide support for the phase shifter 2 and the filter 3.
- the material of the dielectric substrate 1 should be selected from materials with high dielectric constant and low microwave loss, such as a PCB board, i.e. a printed circuit board.
- the phase shifter 2 is arranged on one side of the dielectric substrate 1, and the filter 3 is arranged on the other side of the dielectric substrate 1.
- the phase shifter 2 and the filter 3 can be electrically connected through a metallized via 14 or a wire that passes through the dielectric substrate 1.
- the phase shifter 2 further includes a rotating arm 21 , which is rotatably connected to the first microstrip transmission line 22 , and is in sliding contact with at least one second microstrip transmission line 23 .
- the filter 3 includes at least one fan-shaped open-circuit stub 31 , which is electrically connected in parallel to the first microstrip transmission line 22 , wherein the fan-shaped open-circuit stub 31 is disposed on the second side 12 of the dielectric substrate 1 .
- the slow-wave structure can be a spiral line
- the second microstrip transmission line 23 at this time is a slow-wave microstrip transmission line 24.
- the slow-wave microstrip transmission line 24 also makes sliding contact with the rotating arm 21, so the contact point between the slow-wave microstrip transmission line 24 and the rotating arm 21 can also be set to an arc shape, and the center of the arc coincides with the rotation axis of the rotating arm 21, and two output ends 231 are also set on both sides of the slow-wave microstrip transmission line 24.
- handheld devices include but are not limited to mobile phones, tablet computers, PDAs, wearable devices, etc.
- the embodiments of the present disclosure do not specifically limit the specific types of handheld devices.
