摘要
设计了一种新型的带有频带抑制功能的超宽带单极天线,采用微带馈电,其辐射贴片采用多边形结构,使其在3.1GHz～11.8GHz频带内电压驻波比小于2。分别在辐射贴片和微带馈线上引入两个U形槽谐振结构,使其在5.0GHz～5.9GHz的频带内驻波比大于2,实现良好的频带抑制。
In this paper,A novel Microstrip-fed Monopole antenna having a frequency band-notched function for UWB applications is proposed and studied.The designed antenna uses the polygon structure,and satisfies the VSWR reguirement of less than 2 in the frequency band between 3.1GHz and 11.8GHz.And a pair of U-shaped slots are introduced on the radiator and the microstrip feed-line to achieve frequency notched characteristic at 5.0GHz～5.9GHz(VSWR>2).
