A wideband, pattern-reconfigurable antenna is reported that is, for example, a good candidate for ceiling-mounted indoor wireless systems. Switchable linearly polarized broadside and conical radiation patterns are achieved by systematically integrating a wideband low-profile monopolar patch antenna with a wideband L-probe fed patch antenna. The monopolar patch acts as the ground for the L-probe fed...
This paper introduces several emerging reconfigurable antenna elements for modern broadband wireless communication systems. Firstly, we will present a broadband uni-directional circular polarization (CP) reconfigurable antenna consisting of four planar monopole radiators and an broadband output phase reconfigurable feeding network. Switchable left-handed circular polarization (LHCP) and right-handed...
