摘要
在无线通信系统中,微带天线备受青睐。文章设计的微带四元阵在水平面上有全向的方向图,且极化方式为垂直极化。该天线的每个阵面都是采用串并结合的微带矩形贴片天线形式,并通过短路加载的方式实现天线俯仰面方向图在上半空间绝对增益大于-10.5dBi。测量结果显示,设计的天线在工作频率1090MHz时,电压驻波比小于1.5,方位面最小增益大于7dBi,前后比≥25dB。
In wireless communication applications,microstrip antennas are highly favored.The four element microstrip array designed in this paper has an omnidirectional directional pattern in the horizontal plane,and the polarization mode is vertical polarization.Each array of the antenna adopts microstrip rectangular patch antenna form which is series-and-parallel connection,and it realizes the absolute gain greater than-10.5 dBi in upper half space through short-circuit loading.The measurement results show that,the designed antenna works at 1090 MHz,with the voltage standing wave ratio less than 1.5.Moreover,the minimum gain in azimuth plane is greater than 7 dBi and front to back ratio greater than 25 dB.
