具有谐波抑制功能的多极化微带天线阵设计
Design of Multi-Polarization Microstrip Antenna Array with Harmonic Suppression
摘要
Abstract
This article proposes a polarization reconfigurable antenna array based on switching feeding network.The antenna element adopts a square radiation patch,which is fed by microstrip line slot coupling.By loading a short-circuit column in the center of the feeding structure,the broadband performance can be achieved while effectively sup-pressing the even harmonics.A 2×2 antenna array is optimized and designed by using a technique of series array and parallel array.Two ports of the array are connected to a microstrip branch-line coupler and a microstrip hybrid ring re-spectively,ultimately enabling the switching among four modes:horizontal and vertical linear polarization,left-handed and right-handed circular polarization.The experimental results show that the proposed antenna exhibits good matching characteristics and multi-polarization capabilities within the 2.4～2.5 GHz frequency range of the ISM band.With the simple structure and user-friendly operation,this antenna can be potentially applied to the occasion of antenna polariza-tion diversity in wireless communication systems.关键词
