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。
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.
