This paper introduces a broadband vertical polarization omnidirectional antenna based on stub loading operating in the VHF band. The antenna adopts the method of coupled feeding, uses loading stub ...

This letter proposes a broadband reconfigurable antenna capable of forming single and dual beam radiation, with switchable polarization states. The antenna consists of a reconfigurable power divider ...
