Abstract

This communication presents a substrate integrated waveguide (SIW) switched beam antenna operating at 2.45 GHz. The design allows the beam to be switched between six discrete directions giving 360° coverage. The switch beam control is achieved using only four PIN diodes that are integrated directly to the structure allowing its nature to be electrically controlled. The design is no bigger than a single SIW slot antenna although a perpendicular reflector is used. The antenna is shown to be in good agreement with simulated results achieving measured gains between 3 and 6 dBi.
