Abstract

In this research paper, an effective and efficient optimization technique is utilized for miniaturization of the antenna structure. Earlier research articles have never employed Whale Optimization Algorithm (WOA) for antenna optimization and hence this paper focus to exploit Bio inspired whale metaheuristic algorithm for patch antenna optimization with objective of $\pmb{S_{11} < =}\pmb{-20\ \mathrm{dB}}$. The optimized Quad H slotted antenna has been designed and simulated using ADS. Various performance parameters like return loss, gain, directivity, radiation pattern are analyzed. Impedance and radiation characteristics of the proposed antenna are tested using N9923A vector network analyzer (4 GHz) and in anechoic chamber. It confirms that proposed antenna has attained the minimum return loss −28.764 dB with maximum gain of 5.566 dBi and directivity of 6.510 dBi at the designed frequency 2.45 GHz.

2.45 GHz小型h型开槽天线设计与性能分析

在本研究中，采用了一种有效的优化技术来实现天线结构的小型化。之前的研究文章从未使用鲸鱼优化算法(Whale Optimization Algorithm, WOA)进行天线优化，因此本文重点利用生物启发鲸鱼元启发式算法进行贴片天线优化，目标为$\pmb{S_{11} < =}\pmb{-20\ \mathrm{dB}}$。设计了优化后的四H缝天线，并利用ADS进行了仿真，分析了回波损耗、增益、指向性、辐射方向图等性能参数。利用N9923A矢量网络分析仪(4ghz)和暗室测试了天线的阻抗和辐射特性。结果表明，在2.45 GHz设计频率下，天线的回波损耗最小，达到28.764 dB，最大增益为5.566 dBi，指向性为6.510 dBi。
