Right Hand Circularly Polarized Ku-Band Patch Antenna withImproved Axial Ratio Bandwidth for Small Satellite Application
Abstract: This study presents the design and fabrication of a Ku-band patch antenna that achieves right-hand circular polarization (RHCP) with an enhanced axial ratio (AR) bandwidth. The proposed antenna consists of two circular split ring resonators(SRRs) and a T-shaped feedline. To achieve circular polarization, circular split ring resonators were placed symmetrically at both ends of the T-shaped feedline. The proposed antenna has been carefully designed and simulated using the CST Microwave …
