【摘要】 贴片形状是影响微带贴片天线性能的主要因素,通过仿真设计了一种高增益扇形微带贴片天线。扇形微带贴片天线采用同轴馈电方式,通过有限元法对扇形微带贴片天线在不同参数下的性能进行对比研究。仿真结果表明:扇形微带贴片天线的谐振频率、回波损耗等性能参数符合设计要求,天线的回波损耗小于-10d B。通过对比扇形微带贴片天线在不同尺寸下得到的天线增益,可以得出结论扇形微带贴片天线最高增益为9.17d B,比普通微带贴片天线的增益高了约4d B。更多还原

【Abstract】 A high gain fan-shaped microstrip patch antenn is designed by simulation with considering the main factor which the patch shape affect the performance of microstrip patch antenna. The coaxial feed way is adopted in fan-shaped microstrip patch antenna through the finite element method under different parameters in a fan-shaped microstrip patch antenna performance. The experimental results show that the fan-shaped microstrip patch antenna,the resonant frequency return loss and other performance parameters all meet the design requirements and return loss is less than 10 dB of antenna. By comparing the fan-shaped microstrip patch antenna under different size of antenna gain,it can be concluded that the maximum gain of the fan-shaped microstrip patch antenna is 9.17 dB and taller than the conventional microstrip patch antenna gain about 4dB.更多还原
