An experimental investigation of reconfigurable ultra-wideband (UWB) modified octagonal microstrip monopole patch antenna with switchable and tunable band-notched characteristic is presented in this paper. Notched-bands are obtained by connecting or disconnecting the open shunt stubs. The switching is achieved by using PIN diodes. Additionally, more notch-bands are created by adding additional stubs to the original…

This paper is an extension of the work originally presented at the European Microwave Conference (EuMC) about a reconfigurable hybrid metal-plasma Yagi-Uda antenna operating at 1.55 GHz: this antenna consists of metallic reflector and active element and two plasma directors. The conference work showed through full-wave numerical simulations (CST Microwave Studio) how it is possible…
