Circularly Polarized (CP) antennas are becoming increasingly popular for wireless applications. This paper describes design and simulation of circularly polarized slot patch antenna for C-band applications. C-band has frequency range from 4 to 8 GHz that is used for satellite communication transmissions, some Wi-Fi devices, and cordless telephone. For circular polarization, the axial ratio (AR) less than 3 dB can be produced by inserting a rectangular stub from the ground plane towards the square shaped slot. The simulation results are observed by Ansoft HFSS version 13 software in terms of return loss, VSWR, axial ratio and radiation pattern. Simulated results show that the antenna attains an S11 < -10 dB, return loss bandwidth from (4 GHz to 8GHz) and the axial ratio bandwidth from (4.5GHz to 7.3GHz). The proposed micro-strip slot patch antenna is connected by 50Ω micro-strip feed line and it has been fabricated on FR4 Substrate.

C-band has frequency range from 4 to 8 GHz that is used for satellite communication transmissions, some Wi-Fi devices, and cordless telephone. For circular polarization, the axial ratio (AR) less than 3 dB can be produced by inserting a rectangular stub from the ground plane towards the square shaped slot. The simulation results are observed by Ansoft HFSS version 13 software in terms of return loss, VSWR, axial ratio and radiation pattern. Simulated results show that the antenna attains an S11 < -10 dB, return loss bandwidth from (4 GHz to 8GHz) and the axial ratio bandwidth from (4.5GHz to 7.3GHz). The proposed micro-strip slot patch antenna is connected by 50Ω micro-strip feed line and it has been fabricated on FR4 Substrate.
