摘要

摘要: 微带天线的窄带特性是限制其广泛应用的重要原因之一,如何展宽微带天线的带宽一直受到研究人员的关注.本文提出一种简单、实用、满足工程实际需要的宽频带微带天线的设计方法,实测表明,利用本文提出的设计方法所设计的L波段双层微带贴片天线,其阻抗带宽达到25.7%,在工作范围内增益大于8dB.同时,本文提出的设计方法对于多层贴片微带天线也是适用的.

Abstract: The narrow bandwidth property of a microstrip antennas is one of the main reasons that restrict its wide usage, the way to broaden the bandwidth of microstrip antennas has been concerned by investigators. A simple and practical method for the design of broadband microstrip antennas is proposed in this paper. To confirm the applicability of the method for the designs of the proposed antennas at L-band, experiments have been carried out. The measured results show the proposed antennas have a bandwidth of 25.7%, its gain in operating band is larger than 8dB. Also, the method proposed in this paper is applicable to the design of other mutilayered microstrip patch antennas.
