Polarization Re-Configurable Antenna with Increase Gain for Small Satellites

Future small satellites require the development of reconfigurable antennas. Designing such antennas, especially single port patch antennas with circular polarization is a challenging task. Therefore, we propose both right-hand/left-hand circularly polarized (RHCP/LHCP) antenna which can reconfigure. The proposed follows topology E-shape that single-layer and single-feed two RF switches. switches alter in real-time. We also show various properties antenna, as radiation pattern, impedance matching, axial ratio, bandwidth through simulations measurements. model shows excellent performance agrees well an effective 2.45 GHz–2.82 GHz maximum gain 9.88 dB at 2.55 GHz. symmetry preserved by switching between LHCP RHCP modes.
