Cavity-Less Circularly Polarized Magneto Electric Dipole

Magneto electric (ME) dipole antennas are an innovative solution accommodating high antenna system requirements. In this work, we will study the effect of different shapes of radiating element. This change will adjust the electrical length of the electrical dipole. Consequently, it will enhance the ARBW and enable a reduction in the ground reflector size while maintaining a wide ARBA and high gain across the bandwidth. The circular ME dipole achieves a bandwidth of 62% and (ARBW) of 44%, high gain with a maximum gain of 8.8 dBi at 4.5 GHz, and in-band variation of 1.8 dB.
