Leaky-Wave Antenna with Switchable Omnidirectional Conical Radiation via Polarization Handedness

Reconfigurable antennas capable of beam-steering offer an efficient solution to optimize the use of the crowded wireless medium and can serve as a multifunction antenna. Beam-steering is often achieved by antenna geometry switching at the expense of hardware complexity. Herein, polarization is used to realize beam-steering without the need for antenna geometry modification. Depending on the handed...
