摘要/Abstract

摘要： 采用多种带宽改进技术,应用于不同形状的单层片状天线,主要包括:短路销钉,双宽缝(E形)等。同时,采用基于MOM的软件包分析了天线性能,证明方形天线可以工作在3个频率点,即1.83 GHz、2.16 GHz和2.74 GHz,其最大的增益达到9.4 dB;E形天线工作在2.13 GHz和2.5 GHz,当中心频率为2.4 GHz时,带宽达到33.33%(反射损耗≤-10 dB),其最大增益为9.25 dB。

关键词: 微带天线, 带宽改进, 广带天线

Abstract: Several techniques of ba ndw idth enhancement a re ado pted in this paper fo r dif ferent shapes o f single-lay er single-pa tch antenna. They are mainly: theprobe-fed square patch antenna with sho rting pins, a nd the pro be-fed rectang ular patch antenna wi th a pai r o f wide slit s ( E-sha ped pa tch ) . The a nalyses w ere ca rried out using method o f moments sof tw are packag e. It i s show n that the pro be-fesquare patch a ntenna can be made resonate a t th ree dif ferent f requencies o f 1. 83 GHz, 2. 16 GHz and 2. 74 GHz respectiv ely w ith a peak gain o f 9. 4 dB. The Eshaped pa tch is designed to resonate at tw o di fferent f requencies o f 2. 13 G Hz and 2. 5 GHz wi th ov erall impeda nce bandwidth of about 33. 33% ( return loss≤ - 10dB) wi th respect to a center f requency of 2. 4 GHz. The peak gain i s about 9. 25dB.

Key words: micro st rip pa tch antenna, bandwidth enhancement, broad-band antenna
