A compact monopole antenna with enhanced selectivity is designed based on circular disk monopole antenna and signal interference technique (SIT). It is composed of a circular disk monopole and a SIT‐based filtering structure consisting of two pairs of short‐circuited edge coupled stubs loaded on the feeding line. When the filtering structure is just loaded the feeding line, a filtering monopole antenna is obtained. A prototype is constructed, assembled, and tested. The measured results agree well with simulated one.

全向单极天线基于信号干扰的选择性增强技术

基于圆盘单极天线和信号干扰技术（SIT），设计了一种具有增强选择性的紧凑型单极天线。它由一个圆盘单极子和一个基于SIT的滤波结构组成，该滤波结构由加载在馈线上的两对短边耦合短线对组成。当滤波结构刚加载到馈电线上时，获得滤波单极天线。原型被构造，组装和测试。测量结果与模拟结果吻合良好。
