A Miniature Circular Disc Monopole UWB Antenna with a Tapered Feed Line and a Circular Ground

摘要：

In this paper,a miniature circular disc monopoleUWB antenna implemented on a FR-4 substrate was proposed.The proposed antenna uses a novel designed microstrip feedline and an improved ground shape.The size of total antenna isabout 40×30 mm2,and the radius of radiation element is 6mm.Both the radiation element and the whole antenna aremuch smaller than the conventional antenna with a uniformfeed line and a square ground.The simulated and measuredresults show that a good impedance matching over UWB band(3.1-10.6GHz) was realized.An omnidirectional radiationpattern and gain characteristics of the proposed antenna aregiven.
