Frequency and polarization reconfigurable patch antenna design with varactor diode and branch line coupler feed network is presented. The frequency tuning, achieved tunable impedance bandwidth from 2.34 GHz to 2.68GHz by varying the four varactor diode capacitance value between 12.33pF to 1.30pF and circular polarization using dual probe feed method. Then additional BLC feed network is used to control simultaneously both frequency tunability from 2.05 GHz to 3.13GHz and polarization which is used for S-Band application. © 2017 IEEE.

Frequency and polarization reconfigurable antenna using BLC feed network

2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)

Circular patch antenna for frequency reconfigurable and polarization switching in the antenna using feed configuration is presented. On varying capacitance of the varactor diode from 2.67pF to 0.99pF the antenna tuned from 1.85 to 2.55 GHz impedance bandwidth (32%). The cascaded branch line coupler (BLC) with switching feed configuration is used to achieve polarization reconfiguration (i.e.) vertical linear (VL)/horizontal linear (HL) polarization, RHCP, LHCP in the antenna. The proposed feed network is used to control tunable over a wideband from 1.5 to 3 GHz. The impedance bandwidth of patch antenna is matched with the impedance bandwidth of cascaded BLC feed network to achieve all the performance. © 2019 IEEE.

Circular Patch Frequency Tunable Antenna with Switching Polarization Feed Configuration

Circular microstrip reconfigurable antenna for frequency and polarization with feed configuration is presented in this paper. The wideband cascaded branch line coupler (BLC) with switching feed configuration is used to achieve horizontal linear polarization (H-LP), vertical linear polarization (V-LP), right hand circular polarization (RHCP) and left hand circular polarization (LHCP) in the antenna. The proposed cascaded BLC feed network is used to control tunable over a wideband from 1.25 to 2.95 GHz. The circular patch antenna has the tunable impedance bandwidth from 2.09 to 2.96 GHz. It is achieved by varying the varactor diode capacitance values between 4.15pF (0V) to 0.94pF (6V). The impedance bandwidth of BLC feed network is matching with the impedance bandwidth of patch antenna simultaneously to achieve all the performance. Measured results show good agreement. © 2018 IEEE.
