摘要：

A novel band-rejected ultrawideband (UWB) planar monopole antenna is investigated. By utilizing the resonance nature of folded strips and a new inductive coupling scheme, the antenna demonstrates bandstop-filter-like response with high frequency selectivity and controllable bandwidth at the rejection band. The design methodology is introduced. The simulated and measured results including impedance matching, radiation patterns, and gain responses are investigated. An antenna equivalent circuit model with improved accuracy is discussed as well. When compared with our previous work, the new design demonstrates substantial improvements in many aspects. The argument will be discussed and verified carefully throughout the communication.
