摘要
提出了一种选择性准椭圆带通滤波器天线。所提出的滤波器天线具有低的通带插入损耗和较高的阻带抑制。该结构由准椭圆带通滤波器与贴片天线直接耦合组成。带通滤波器由四个(λ/4)螺旋方形谐振器组成。它在(3.25-3.6)GHz之间工作,因此适用于WiMAX应用。利用CST Microwave Studio Suite软件对滤波器天线电路进行了仿真。贴片天线的仿真结果与滤波天线的仿真结果吻合较好。
Design of a Selective Filter-Antenna with Low Insertion Loss and High Suppression Stopband for WiMAX Applications
This paper presents a selective quasi–elliptic bandpass filter-antenna. The presented filter-antenna has a low insertion loss in the passband and relatively high stopband rejection. This structure consists of a quasi–elliptic bandpass filter direct coupled with patch antenna. The bandpass filter consists of four (λ/4) spiral square resonators. It has operates between (3.25–3.6) GHz so it is suitable for WiMAX applications. A CST Microwave Studio Suite software has used to simulate the filter-antenna circuit. The simulated results of the patch antenna and the results of the filter-antenna appears a good matching between the two circuits.
