摘要
Abstract
A novel Ka band circular-polarization microstrip antenna is proposed.The antenna is coupled-fed by L-shaped apertures in the ground plane to realize circular-polarization.The antenna array is analyzed and optimized,then the array is made and measured.Simulated and measured results show the feasibility of the proposed design.Simulated results of the relative impedance bandwidth and axial-ratio bandwidth are 3.9% and 2% respectively,and measured results are 4.2% and 3.5%.With good circular polarization performance,the antenna can be used in satellite communication.关键词
