摘要

提出了一种GSM 900 MHz垂直极化多波束天线试验台，该试验台采用4波束微带平面天线、GSM移动电话、GSM基站、DSP和个人计算机控制测量过程。多波束天线覆盖120/spl度/方位角，4个波束提供阻抗带宽>10%，每个波束的最小增益为15.8 dBi，尺寸为710/spl倍/800/spl倍/ 12mm。静态波束形成是在射频(RF)下进行的。结果表明，载波干扰(C/I)的改善以及接收信号强度指示(RSSI)的增加。

A GSM900 multibeam antenna system test bed for capacity and range improvement trials

A GSM 900 MHz vertically polarised multibeam antenna testbed is presented incorporating a thin 4 beam microstrip planar antenna, a GSM mobile, a GSM base station (BS) a DSP and a personal computer (PC) to control the measurement procedure. The multibeam antenna covers 120/spl deg/ in azimuth with 4 beams offering an impedance bandwidth >10%, a minimum gain of 15.8 dBi for each beam and has dimensions of 710/spl times/800/spl times/12 mm. The static beamforming is performed at the radio frequency (RF). The results demonstrate a carrier to interference (C/I) improvement together with increased received signal strength indication (RSSI).
