Abstract

In this paper, a compact ultra-wideband patch antenna with dual-band rejection is proposed. The proposed antenna filters 3.3-3.8 GHz WiMAX and 5.15-5.85 GHz WLAN by respectively rejecting these bands through a C-shaped slit and a λg/4 resonator. The λg/4 resonator is positioned as a pair, centered around the microstrip line, and a C-type slit is inserted into an elliptical patch. The impedance bandwidth of the proposed antenna is 2.9-9.3 GHz, which satisfies the bandwidth for ultra-wideband communication systems. Further, the proposed antenna provides dual-band rejection at two bands: 3.2-3.85 and 4.7-6.03 GHz. The radiation pattern of the antenna is omnidirectional, and antenna gain is maintained constantly while showing -8.4 and -1.5 dBi at the two rejected bands, respectively.

摘要

本文提出了一种具有双频段抑制功能的紧凑型超宽带贴片天线。所提出的天线通过一个C形缝隙和一个λg/4谐振器分别抑制3.3 - 3.8 GHz的WiMAX频段和5.15 - 5.85 GHz的WLAN频段。λg/4谐振器成对设置，以微带线为中心，并且在椭圆形贴片上插入一个C型缝隙。所提出天线的阻抗带宽为2.9 - 9.3 GHz，满足超宽带通信系统的带宽要求。此外，所提出的天线在3.2 - 3.85 GHz和4.7 - 6.03 GHz两个频段提供双频段抑制。天线的辐射方向图是全向的，并且在两个抑制频段分别保持-8.4 dBi和-1.5 dBi的恒定天线增益。
