Abstract
A novel design of S-band based circularly polarized small satellite patch antenna is presented. It comprises three slots and an overall dimensions of 98 mm x 98 mm. The antenna has been designed for an impedance of 50 ohm and shows optimum performance for frequency range of 2.3 GHz to 2.5 GHz. Absolute gain observed is 7.8 dBi with main lobe at 20 normal to the antenna plane, making it close to unidirectional antenna. A diamond shaped patch with suitable location of coaxial feed allows the antenna to be circular polarized. Additionally, three identical slots were embedded in the radiating patch to obtain the high bandwidth compact antenna with right circular polarization. The variation of feed position allows switching between Left and Right Hand Circular Polarization (LHCP, RHCP) with 5.48 dBi gain. The S11 parameter was measured using Network Analyzer and similar results were obtained as software simulation output. The designed antenna is compatible with CubeSat configuration and hence can be used for various small satellite applications.
