摘要

介绍了一种工作在5.1 GHz的紧凑型带通(cid:12)滤波天线。辐射层由u型贴片和三叉戟谐振器组成。u形贴片既是天线又是(cid:12)信源的最后一级，由三叉戟谐振器的插入耦合部分激发。为了改善阻抗匹配和下阻带抑制，采用了缺陷接地结构(DGS)。该天线尺寸为0:36 (cid:21) 0 (cid:2) 0: 36 (cid:21) 0 (cid:2) 0: 01 (cid:21) 0 ((cid:21) 0为5.1 GHz波长)，没有复杂的外部馈电结构，具有足够的带宽，良好的频率裙边选择性和(cid:13)通带响应。测量结果表明，阻抗带宽为110 MHz，峰值增益为3.88 dBi。此外，(cid:12)滤波天线还具有急剧的滚降率和令人满意的带外抑制水平。

A Compact Single Layer Filtering Antenna with DGS for 5.1 GHz Application

|A compact bandpass (cid:12)ltering antenna operating at 5.1 GHz is introduced. The radiation layer makes up of a U-shaped patch and a trident resonator. The U-shaped patch is both the antenna and the last stage of the (cid:12)lter, which is excited by the insertion coupling part of the trident resonator. To improve the impedance matching and lower stopband suppression, a defective ground structure (DGS) is used. The dimension of the antenna is 0 : 36 (cid:21) 0 (cid:2) 0 : 36 (cid:21) 0 (cid:2) 0 : 01 (cid:21) 0 ( (cid:21) 0 is the wavelength at 5.1 GHz) without a complex external feed structure, which has enough bandwidth, a good frequency skirt selectivity, and a (cid:13)at passband response. The measurement results manifest that the impedance bandwidth is 110 MHz, and the peak gain is 3.88 dBi. In addition, the (cid:12)ltering antenna also has a sharp roll-oﬀ rate and a satisfactory level of out-of-band suppression in the stopband.
