摘要：

A simple ultra-wideband planar rectangular printed monopole antenna with dual narrow band-notched characteristics is presented in this paper. Dual narrow band-notched frequencies at 3.4 GHz and 5.2 GHz are achieved by embedding a U-shaped slot in the radiation patch and a small pentagon patch on the ground, respectively. Moreover, input impedance, conceptual equivalent circuit models and surface current distributions are built for analysis and explanation of dual narrow band-notched characteristics. At the same time, an approximate expression of the notched frequency with the pentagon patch dimension is proposed in this paper. The designed antenna operates over the frequency band between 2.69 GHz and 12 GHz (126.8%), with one narrow notched band from 3.32 GHz to 3.55 GHz (6.7%) and the other from 5.04 GHz to 5.39 GHz (6.8%). The antenna is successfully simulated, fabricated and measured, showing broadband matched impedance, dual narrow band-notched characteristics, stable gain, high radiation efficiency and omni directional radiation patterns.
