RESUMO

Abstract The presented model for wideband circularly polarized microstrip antenna is an improved version of the previous models which is widely applicable to satellite, microwave relay and radar. The designed circularly polarized antenna having overall volume of 20× 20 × 1.6 mm3 actively works at the impedance bandwidth of 9000 MHz (4.0–12.9 GHz) having 105%(with 8900 MHz taken as center frequency). The 3-dB axial ratio bandwidth is obtained as 5500 MHz (5.4–10.9 GHz) depicting 67.5% (with 8150 MHz taken as the center frequency). Measured results of impedance bandwidth, axial ratio, gain and VSWR agrees to the simulation results.
