圆极化五边形微带天线阵的设计与仿真
Design and simulation of circular polarization micro-strip antenna array
摘要
Abstract
Pentagon circular polarization micro-strip antenna is good in broadband and circular polariza tion characteristics but hard in design process. The design principle of the pentagon circular polarization micro-strip antenna is researched and single ended side feeding method is presented. The way to analyze polygon micro-strip antennal is given, which is named finite cell. By means of adjust the 5. 6 GHz penta gon circular polarization micro-strip antenna, HFSS simulation results are shown. Based on the penta gon antenna unit be simulated, a four element antenna array is presented. Design method for feed net of the array is given. Design is optimized by HFSS software, and simulation results for the array are dis played. Simulation results show that the array obtain a 4% 3 dB bandwidth, and 12 dB gain.关键词
