摘要
设计了一种工作于高次模的矩形微带天线。该天线采用同轴探针进行双馈电,以激励起TM02模和TM20模产生全向性锥形波瓣方向图。使用HFSS13仿真软件进行仿真,实测结果表明,在2 320~2 370 MHz带宽范围内,天线方向图具有全向性锥形波瓣,电压驻波比小于1.8,增益为4.5dBi,最大辐射方向不圆度为2.4dB。
A micro-strip antenna operating at higher order modes is designed. The antenna is fed by two coaxial probes, and its TM02 and TM20 modes which are used to generate omnidirectional conical beam pattern could therefore be excited. Simulations are carried out by using high frequency structure simulator 13 （ HFSS13）. The measured results show that with in 2 320 - 2 370 MHz frequency band, the proposed antenna can achieve omnidirectional conical beam pattern , voltage standing wave ratio is less than 1. 8, the antenna gain is 4. 5 dB, and the pattern ripple is 2. 4 dB at the pattern peaks.
