Due to high loss at this frequency, highly directional, narrow beam antennas are required. Therefore, for WLAN applications where hemispherical coverage is required, a multi-antenna-element solution is required. In response to these requirements, a switchable waveguide structure was built by combining substrate integrated waveguide technology with controllable reflectors.
