A Circularly Polarized Dual-frequency Square Patch Antenna for TT&C Satellite Applications
In this paper, a circularly polarized, dual-frequency, slotted square patch is designed with probe feeding mechanism to operate as the telemetry, telecommand and control (TT&C) antenna for satellite spacecrafts at 2.25 GHz and 3 GHz. This antenna is designed and optimized using 3D EM modeling. Several optimizations are performed to obtain the optimum values of the antenna physical parameters. Then a prototype is fabricated on a low loss teflon microstrip substrate and measured using VNA. Measurements are in great agreement with simulations, which verifies the design procedure and strongly recommends the proposed structure for TT&C satellite system applications.
