Performance and Radiation Patterns of a Reconfigurable Plasma Corner-Reflector Antenna

A novel reconfigurable plasma corner reflector antenna is proposed to better collimate the energy in forward direction operating at 2.4 GHz. Implementation of a low-cost plasma element permits beam shape to be changed electrically. The maximum measured gains are 5.7, 10.8, and 10.5 dBi for the omnidirectional, single-, and double-beam shapes, respectively.
