Novel compact semi annular polygons ultra-wideband microstrip antenna

抄録

This paper presents the results of a novel ultra-wideband (UWB) annular elliptical antenna with multi resonant rings which are fed via coplanar waveguide (CPW). The proposed antenna exhibits an impedance bandwidth of 163% covering an ultra-wideband frequency range from 2 to 20GHz, with a return-loss performance of better than -10dB (S11 ≤ -10dB). Details of the antenna design, simulation and measured results are presented.
