摘　　要：文中设计了一种可用于GSM900/DCS1800的双频双环形天线。该天线由两个并排的环形天线构成,在天线中加入的断路片和反射杆实现了阻抗匹配和单向辐射特性。实验结果表明,分别在800～1000MHz和1716～2040MH两个频段内,天线获得了良好的输入特性和辐射特性。该天线适用于GSM900/DCS1800手机信号,以及PHS1905MHz信号的传输。A dual-loop antenna with dual-band frequency range is designed. The proposed antenna is composed of two loop antenna constructed side by side, and the short patch and reflection pole is added so that the good impedance matching and single radiation performance is achieved. The experimental results shows that in both 800- 1000MHz and 1716-2040MH frequency range, this antenna obtains good input performance and radiation performance. The proposed antenna is suitable for GSM9OO/DCS1800 mobile telephone signal and PHS1905MHz signal propagation.
