| 摘 要： | 提出了一种应用于无线局域网（WLAN）的新型双频天线。该天线采用微带线馈电的方法,其辐射面呈阶梯形,接地面为＂工＂型宽缝结构,可以覆盖IEEE802.11a/b/g（2.4～2.484GHz,5.15～5.825GHz）频段标准。其回波损耗小于10dB的阻抗带宽在2.4GHz频段可达160MHz（2.4～2.56GHz）,在5GHz频段的可达1.32GHz（5.05～6.37GHz）。整个天线在42mm×52mm、介电常数为4.5、厚度为1.5mm的FR4介质基片上实现。结果表明,该天线具有十分良好的应用潜质。

| Abstract: | A novel dual-band antenna for WLAN is proposed in this paper.The antenna,with the step-shape radiation surface and ＂H＂-type slot in the ground,is fed by the microstrip line,and could cover the working bands of IEEE 802.11a/b/g（2.4～2.484 GHz,5.15～5.825 GHz）.The impedance band with less than 10 dB of return-wave loss could reach 160 MHz in 2.4 GHz and reach 1.32 GHz in 5 GHz.The antenna is realized with FR4 in 42 mm（W）× 52 mm（L）.The measurement results show that the proposed antenna is of good application potential in WLAN system. |
