Design and Improvement Measure of a New Dual Band Multipolarization Antenna Using a SingleLayer Substrate for C Band Applications

Abstract

A novel dual-band multipolarization slotted patch antenna with a single-layer substrate and one feeding port for C-band applications is presented. The measured results show that impedance bandwidth in which return loss is less than −10dB is from 5.7 GHz to 6.1 GHz and from 7.5 GHz to 7.8 GHz. The Axial Ratio (AR) of the antenna is < 3dB and allows the both right-handed (RH) and left-handed (LH) circular polarized (CP) from 7.6 GHz to 7.8 GHz and from 7.5 GHz to 7.6 GHz for linear-polarization. The radiation pattern is quasi-directional on the greater part of the working band. The software CST Microwave studio is used for simulation which results are in great agreement with the measured parameters. The proposed antenna can be used in occasions where the antennas need to have dual band and multi-polarization for its advantages of compact structure and low cost.
