摘要

本文提出了一种新型双带陷波单极天线和半贴片宽带圆形微带天线。为了获得这一特性，在圆盘单极子超宽带天线中嵌入了两个优化的弧形槽。采用普通型圆盘单极天线实现宽阻抗带宽。实现了全向辐射方向图，使所提出的天线能够用于通信系统。基于嵌入一对双圆槽的超带宽全贴片微带天线，将贴片辐射器切去一半得到半贴片天线。与全贴片天线相比，半贴片天线具有相似的阻抗带宽，且尺寸紧凑，成本更低。

Design of novel dual band-notched disk monopole antennas

This paper presents a novel monopole antenna with dual band-notched characteristics and a half-patch broadband circular microstrip antenna. To obtain this feature, two optimized arc-shaped slot is embedded to the disk monopole UWB antenna. The normal type of disk monopole antenna is used to achieve the wide impedance bandwidth. An omnidirectional radiation pattern is also achieved, which enables the proposed antenna to be used in communication systems. Based on the full patch microstrip antenna which has ultra bandwidth for embedding a pair of double circular slots, the half patch antenna is obtained by cutting away half of patch radiator. The half patch antenna has the similar impedance bandwidth compared with the full patch antenna, with compact size and lower cost.
