【摘要】 为了适应现代双频通信系统的要求,双频天线必须具有小尺寸和频率易调的特点。通过在H形微带天线的辐射边附近采用U形缝隙加载,在单层微带天线上实现了双频效果。和常规的双频微带天线相比,该天线的尺寸可以大大减小。通过改变天线的尺寸参数,高频段和低频段可以很容易的调节,本设计中得到的频率比范围是1.716---2.363。该天线在两个频段有相同的极化平面和较宽的辐射波束。
【Abstract】 To satisfy requirements of modern dual-frequency communication systems.the antenna should have the characteristics of compact size and easy frequencies tuning.A novel compact single layer dual-frequency microstrip antenna is designed in this paper,which used an H—shaped geometry with four U—shaped slots embedded near the radiation edges.This antenna can realize a significant size reduction comparing to regular dual-frequency microstrip patch antenna.The lower and higher resonant frequencies can be tuned easily by changing the design parameter,and a various frequency ratios(1.71 6~ 2.363)can be obtained in the design.For the two operating frequencies of the proposed antenna,the same polarization planes and broadside radiation patterns are obtained.
