摘要

本文提出了一种基于改进裂环谐振器(SRR)和改进互补裂环谐振器(CSRR)作为缺陷接平面的三波段微带贴片天线的实现方法。天线设计在介电常数为4.4的FR4衬底上，尺寸为35 mm × 35 mm × 1.6 mm，总设计天线体积为1960 mm3。通过在贴片中引入的多个谐振器，在天线中引入多波段操作。阻抗匹配是通过局部地平面和修正的小波比来实现的。利用高频结构模拟器(HFSS)软件对天线的仿真性能进行了验证。设计的天线谐振频率分别为2.8 GHz、5.8 GHz和6.9 GHz，可满足WiMAX、ISM和Sub-7 GHz无线通信的应用需求。该天线采用印刷电路板(PCB)格式制作，利用矢量网络分析仪(VNA)测量其回波损耗特性。所提三带天线的测量结果与模拟回波损耗特性吻合较好。

A Triband Compact Antenna for Wireless Applications

This paper presents the implementation of a triple band microstrip patch antenna based on modified split ring resonator (SRR) and modified complementary split ring resonator (CSRR) as defected ground plane. The antenna is designed in a FR4 substrate of dielectric constant 4.4 with dimensions as 35 mm × 35 mm × 1.6 mm that comprises a total designed antenna volume of 1960 mm3. Multiband operation is introduced in the antenna through multiple resonators that are introduced in the patch. Impedance matching was provided with the help of partial ground plane and modified SRR in patch. The simulation performance of the antenna is verified using high frequency structural simulator (HFSS) software. The designed antenna resonates at 2.8 GHz, 5.8 GHz, and 6.9 GHz for the application requirements of WiMAX, ISM, and Sub-7 GHz wireless communication. The antenna is fabricated as printed circuit board (PCB) format, and its return loss characteristics are measured using a vector network analyser (VNA). The measurement results of the proposed triband antenna are in good agreement with simulated return loss characteristics.
