Abstract

Using 2 L-probe antennas as elements, the dual-band can be operated in GSM/PCS systems. The antenna can be used in a GSM/PCS indoor base station with operation frequencies of 900 MHz and 1.8 GHz. The copper rod is employed as an air transmission line and a short pin is employed as DC ground. The technique of L-probe fed patch antenna is employed for design of a dual-band antenna due to its several advantages: low cost, lightweight, ease of fabrication and wide bandwidth. An impedance bandwidth of 15% (lower-band) and 11% (upper-band) (SWR/spl les/1.5) and average gain of 6 dBi have been achieved.

移动通信用双频l探针贴片天线的设计

采用2个l探测天线为单元，可在GSM/PCS系统中双频工作。该天线可用于GSM/PCS室内基站，工作频率为900mhz和1.8 GHz。采用铜棒作为空气传输线，采用短引脚作为直流接地。采用l探针馈电贴片天线技术设计双频天线，具有成本低、重量轻、制作方便、带宽宽等优点。阻抗带宽为15%(下频带)和11%(上频带)(SWR/spl les/1.5)，平均增益为6dbi。
