摘要 本文提出了一种紧凑型微带线馈电的适用于无限局域网(WLAN)的双频天线,并获得了5.2GHz和5.8GHz的工作频点.该天线印刷在单层,介电常数为2.65的介质板上;天线尺寸为15mm×12mm×1mm.该天线由印制在介质板正面的倒置"土"字型贴片和背面开缝切角贴片组成.仿真和测试结果表明,该天线具有较好的双频工作特点,其阻抗带宽分别为210MHz(5.17～5.38GHz)和318MHz(5.68～6.02GHz).该天线在双频工作点上的最大增益为别为1.75dBi和2.32dBi,且具有较好的全向辐射特性. A compact size microstrip-line fed patch antenna used for WLAN operating at 5--GHz is pro- posed. The antenna consists of with horizontal ＂H-shapped＂ patch on the top side, and the I-slot patch with two cuts on the bottom side. The antenna is printed on a single-layer substrate with a dielectric constant of 2.65 and the overall size is 15 mm × 12 mm × 1 mm. The simulated and measured results show good dual-frequency selection, with impedance bandwidth （return loss -10 dB definition） of 210 MHz （5.17-5.38 GHz） and 318 MHz （5.68-6.02 GHz）, with the gains of 1.75 dBi and 2.32 dBi, respectively. The radiation patterns of the dual-frequency antenna are omnidirectional.
