High-gain L probe-fed planar and cylindrical patch antenna for X band applications

Abstract

L probe provides a huge amount of impedance bandwidth by mounting the patch on a planar and cylindrical substrate. A parametric study and a comparative analysis between planar and cylindrical patch has been presented. Both planar and conformal patches have been designed in X band frequency. Around 2.65 GHz and 3 GHz impedance bandwidth and about 9.66 dBi and 8.37 dBi average gain has been achieved for both planar and conformal antenna, respectively. A stable radiation patterns across the pass band in both the antennas is observed. Design parameters and its effects have been thoroughly studied. Resonant input impedance is plotted. All the simulation work has been carried out in CST EM Simulation Software.
