摘要

本文给出了一种2.4 GHz贴片天线阵列的设计和仿真结果。该天线由一个线性阵列和六个串联馈电贴片天线组成。在雷达和智能天线的应用中，为了避免干扰和提高天线阵列的增益，使用高增益和低副瓣的天线是非常重要的。本研究的目的是利用凯泽-贝塞尔振幅系数设计一种在方位角上尽可能抑制副瓣的天线阵列。我们设计的天线在2.4 GHz频率下的增益为15.1 dB，角宽度为14.6°。测得的10db回波损耗带宽等于18.7 MHz。利用CST MICROWAVE STUDIO 2014对贴片天线阵列进行了分析。

2.4 GHz micro-strip patch antenna array with suppressed sidelobes

In this paper, we present the design and simulated results for a patch antenna array at 2.4 GHz. The antenna consists of one linear array with six series-fed patch antennas. In radar and smart-antenna applications it is very important to use antennas with high gain and low sidelobes in order to avoid the interference and to increase the gain of antenna array. The aim of this research is to design an antenna array that has suppressed sidelobes as much as possible in azimuth by using Kaiser-Bessel amplitude coefficients. Our designed antenna has a gain of 15.1 dB with an angular width of 14.6° at a frequency of 2.4 GHz. The measured 10 dB return loss bandwidth equals 18.7 MHz. Patch antenna array is analyzed using CST MICROWAVE STUDIO 2014.
