A Reconfigurable Antenna With Beam Steering and Beamwidth Variability for Wireless Communications

A reconfigurable antenna (RA) capable of steering its beam into the hemisphere corresponding to θ ∈ {-40°, 0°, 40°}, φ ∈ {0°, 45°, 90°, -45°}, and of changing 3 dB beamwidth, where θ ₃ dB ∈ (40°, 100°), φ ∈ {45°, 90°, -45°} for broadside direction is presented. The RA operating in 5 GHz band consists of a driven patch antenna with a parasitic...
