A novel beamwidth reconfigurable antenna

A novel beamwidth reconfigurable antenna is presented. The design methodology uses tunable strip gratings placed on the sides of a magneto-electric (ME) dipole along its H-plane. A fully functional prototype with an as wide as 40% impedance bandwidth (for SWR ≤ 1.5) is developed and tested, demonstrating the H-plane beamwidth with a tuning range from 81° to 153°. With the wide beamwidth variation and wide impedance bandwidth, the antenna is attractive for stationary terminals and base stations in mobile communications.
