Circularly Polarized Stacked Microstrip Patch Antenna for Satellite Applications
This paper presents design of circularly polarized Circulo-rectangle Patch with Stacked Circular patch Antenna operating at 11.25GHz to 15.08 GHz. Proposed antenna is fabricated on FR4 epoxy substrate having dielectric constant of 4.4. Simulation results show that antenna is tuned at 14 GHz resonant frequency and provides 28.76% bandwidth and 4.37 dB gain. This antenna finds applications in satellite applications, radio astronomy service, radiolocation service and radio navigation applications. The antenna is simulated on HFSS virtual tool.
