Definitions
- GHz gigahertz
- wireless communicating systems which are increasingly used daily, and often almost permanently, by an ever-increasing user population, all have antennas for receiving and, more often than not, to transmit signals in the frequency band defined by the technical standard that governs them. It is mainly mobile phones, especially those obeying the so-called GSM standard, acronym for "global” System for mobile communications "which defines a communication standard whose geographical coverage is worldwide.
- GPS Global positioning system
- the wireless network can instead be designed to cover only a small geographical area, or very limited, such as the so-called “Bluetooth” standard that allows communication up to ten meters of terminals between them.
- Bluetooth a wireless local area network
- WiFi wireless local area network
- the antennas of the above devices must nevertheless be able to maintain optimum efficiency in the entire band of frequencies where they must operate. This efficiency depends on losses which are intrinsic to the antenna and which are measured most commonly using the so-called "S" parameters, of the English “scattering parameters” which make it possible to qualify the behavior of the antenna between the propagation medium on the one hand and the electronic control circuit on the other hand.
- S parameters have been designed and are used to measure and qualify the behavior of passive or active linear circuits operating in the frequency range referred to above often referred to as microwave or radio frequency (RF) in the technical literature. on these topics.
- the adaptation of the antenna is defined in particular by the parameter S1 1 which represents the losses by reflection of the antenna. He speaks in decibels (dB). The lower the value of S1 1, the better the adaptation and therefore the better the overall efficiency of the antenna.
- the parameter S1 1 which is frequency dependent, makes it possible to define the bandwidth of the antenna, that is to say the frequency band in which S1 1 remains below a given threshold which is typically defined at a given level. from -6dB. Under these conditions, a quarter of the power delivered by the electronic control circuit is lost by reflection and three quarters are therefore usefully radiated by the antenna.
- the bandwidth of an antenna can be more or less wide. It is often expressed as a percentage of its center frequency. An antenna whose bandwidth is a few percent is considered to have a narrow band of operation. This type of antenna is well suited for certain applications. For example, for a GPS receiver, an antenna whose bandwidth is of the order of 2% is sufficient.
- An antenna with a bandwidth equal to or greater than 15% is considered to have a wide bandwidth. Those whose bandwidth is greater than or equal to 20% benefit from a very wide bandwidth. Note that to qualify this type of antennas the acronym "UWB”, the English “ultra wide band”, is also often used.
- a very broadband antenna potentially offers many advantages.
- a single broadband antenna can then simultaneously cover several radio frequency standards. This makes it possible to reduce the number of antennas that must be able to be implemented in multiservice wireless devices such as smart phones, which not only gives a certain cost advantage but also makes it possible to overcome technical problems that are difficult to overcome. otherwise solve the parasitic couplings that can occur between the different antennas of the same smart phone.

- Figure 1b illustrates the case where the antenna itself is placed on a separate component 121 to facilitate the integration of the radiofrequency solution. It is then typically a ceramic module which is itself soldered to the PCB. The realization of the adaptation 1 13 between the antenna 121 and the radiofrequency chip 1 15 still requires the intervention of specialized personnel.
- Figure 1c illustrates that most commonly in conventional solutions, radiofrequency chip and antenna occupy separate surfaces, 131 and 133, which do not overlap. This is done by extension of the substrate 134 constituting the PCB.

- the additional constraint imposed on this approach is that the thickness of the assembly 220 must not be substantially greater than in the case illustrated in Figure 1c where the antenna 1 1 1 is placed on an extension of the substrate 134. This is so that the radiofrequency chip 1 15 can always be integrated into communicating equipment of the tablet type of very small thicknesses.

These techniques are inexpensive and compatible with mass production. It will be noted here that for reasons of mechanical stability during assembly, additional tabs (not shown) can be made during cutting. These tabs, which are neither connected nor coupled to any metal layer of the substrate 410, do not disturb the operation of the antenna 310. role is limited only to ensure a mechanical maintenance of the latter during assembly.
