“…Multiple diodes were also mentioned in the past for polarization agility [27,28] and also for dual frequency operations [31]. Modern polarization agile microstrip antennas use only a SPDT switch with a hybrid coupler to limit design complications and efficient operation [36]. polarization agility is In most of the previously mentioned papers, the diode is modelled inside a hole similar to a via or shorting post, and may have been difficult to solder.…”

Abstract-An extended transmission-line model is presented for an inset-fed rectangular microstrip patch antenna. The transmission-line model agrees to the cos 4 impedance variation for inset-fed microstrip antennas with an addition of a corrective extended feed length upto the inner radiating edge. Verification of the model's complex reflection coefficient is concluded with good agreements with measured results. Further extension of the transmission-line model with for or more thin shorting post connected to multiple varactor diodes have been conducted. Fourty two test cases across five independent antenna designs have been worked upon. Results obtained using the transmission-line model are compared with those obtained with a 3D full-wave solver and measurements. In 69% of the test cases, the transmission-line models have less than 3% deviation to the measured or simulated results. 41% of them have less than 1% deviation. For the first two antennas, both simulated and measured results were compared with the transmission-line model. For the rest of three, results from the transmission-line model were compared to the simulated ones.

“…The recent advances in the development and the implementation of RF/microwave switches have permitted the birth of a new concept of the antenna as a device that can dynamically adapt its behavior to different measurements situations and operational contexts, thanks to the change of its main parameters such as: input impedance, frequency band, radiation pattern [1][2][3][4][5][6][7][8][9][10][11][12].…”

Abstract-This paper deals with the design and numerical analysis of a reconfigurable antenna implemented according to the total geometry morphing approach. The reconfigurable antenna is designed so to resemble a reference bowtie antenna, suitable for a stepped frequency Ground Penetrating Radar (GPR) applications, with geometry variable in order to work in different operative conditions. In particular, the good agreement between the reference antenna and the reconfigurable one is tested within the work frequency band 0.3-1 GHz for both the free-space and half-space geometry. Finally, a trial of the reconfigurability of the proposed solution is shown for operative conditions with antenna in contact with different dielectric media.

“…Therefore, we have tried to develop an array antenna capable of electronic beam scanning with small deviation in antenna gain at large angles. For the antenna element, notch [4], dipole, slot line [5][6][7], and patch antennas [8] have been compared because they require limited mounting space and crosspolarisation. The dipole antenna was selected.…”

Abstract-A active phased array antenna has been developed that is capable of wide scanning angle with small deviation in antenna gain using printed dipole antennas with parasitic element, which may have the capability of adjusting the influence of mutual coupling in the array element pattern. The design of the parasitic element is examined and the effect of its shape on pattern characteristics is confirmed. Beam scanning angles of 58 degrees in the ϕ = 0 • plane were obtained for each array antenna pattern.
