摘要

本文对各种带四分之一波馈线的矩形贴片天线的辐射参数进行了相对分析。每个天线基面上分别加入星形和扇形电磁带隙(EBG)。所设计天线的谐振频率为5.25 GHz。所提出的扇形EBG天线具有244 MHz的宽带宽，可覆盖IEEE 802.11a无线局域网(WLAN) (5.125-5.395 GHz)和高性能局域网1 (HIPERLAN/1) (5.150 GHz - 5.350 GHz)等无线应用。该天线还覆盖了全球微波接入(Wi-MAX) (5.25-5.85GHz)互操作性的很大一部分，具有相对健康的7.15 dB增益和显著的辐射效率。本文还提出了通过安装EBG结构来减小贴片尺寸的方法。利用基于时域有限差分法的CST MWS软件暂态求解器进行了设计和仿真。

On the Design of Effective EBG Structures to Model Highly Efficient Rectangular Patch Antenna for Wireless Applications

The paper deals with relative analysis of radiation parameters of various rectangular patch antennas with quarter wave feed line. Star shaped and fan shaped Electromagnetic Band Gap (EBG) are incorporated separately on base plane of each antenna. Resonant frequency apprehended for the designed antennas is 5.25 GHz. The proposed fan shaped EBG based antenna exhibits a wide bandwidth of 244 MHz covering wireless applications like IEEE 802.11a Wireless Local Area Network (WLAN) (5.125–5.395 GHz) and High Performance Local Area Network type 1 (HIPERLAN/1) (5.150 GHz– 5.350 GHz). The antenna also covers a well portion of Worldwide interoperability for Microwave Access (Wi-MAX) (5.25-5.85GHz) with comparatively healthy gain of 7.15 dB and noteworthy radiation efficiency. Size reduction of patch with the installation of EBG structures has also been brought forward in this work. The design and simulation has been carried out using FDTD method based transient solver of CST MWS software.
