摘要: A new broadband millimetre-wave reflectarray antenna structure utilizing novel polarization insensitive multi resonant unit cells is proposed. The design frequency of the RA set at 30 GHz, and it consists 20×20 independent (UCs), which are illuminated by pyramidal horn antenna. cell this array contains two concentric rings combined with a cross loop strips inside for bandwidth enhancement. For maximum aperture efficiency realized gain, placed F to obtain F/D=0.4. simulation results show that obtained gain 25.1 dB slight variation over operating range good cross-polarization level.
