An asymmetrical structure for printed SWB antenna miniaturization

An asymmetrical structure is proposed for miniaturization of super wideband (SWB) antennas. This type of antenna consists of an optimized ground plane and an elliptical semi-monopole. Simulation results show that an example antenna has 2:1 VSWR bandwidth from 0.47 GHz to 25GHz, giving a ratio impeda...

Description
Summary:An asymmetrical structure is proposed for miniaturization of super wideband (SWB) antennas. This type of antenna consists of an optimized ground plane and an elliptical semi-monopole. Simulation results show that an example antenna has 2:1 VSWR bandwidth from 0.47 GHz to 25GHz, giving a ratio impedance bandwidth of more than 50:1.
