Abstract
A wide-beam right-hand circularly polarized(RHCP)antenna based on a double-layer metallic patch structure is proposed to meet the requirements of satellite communication.The antenna operates in the frequency band of 25.5-25.9 GHz and achieves a maximum impedance bandwidth of 2 GHz.An 8×8 antenna array with a square grid arrangement is designed and fabricated.Simulation and measurement results show that the array maintains a gain drop of less than 3 dB over a scanning range of±60°.Within the±60° conical scan volume,the average element gain exceeds 0 dB,and the axial ratio(AR)remains below 3 dB.The isolation between adjacent elements is greater than 15 dB.The proposed array demonstrates structural simplicity and ease of fabrication,with measured results in close agreement with simulations.These results indicate that the antenna is well suited for wide-angle circularly polarized beam scanning applications.关键词
