Slotted waveguide - Wikipedia A slotted waveguide has no reflector but emits directly through the slots. The spacing of the slots is critical and is a multiple of the wavelength used for transmission and reception. The effect of this geometry is to form a high gain antenna that is highly directional in the plane of the antenna. Slotted Waveguide 802.11b WLAN antennas - Trevor Marshall Slotted Waveguide Antennas. Unlike wideband antennas like the biquad, slotted waveguides are resonant antennas, and have a relatively narrow operating frequency range.The designs I am describing on this page have an adequate bandwidth for any WLAN, but they have been carefully designed and must be equally carefully constructed.

A new kind of dual-band and high gain waveguide slot antenna is designed in this paper. By combining a folded plate and a double-layer metal structure with four apertures on its top floor, the proposed antenna has a dual-band characteristic and its gain reaches up to 11.9 dB with only 35 degrees (HPBW) of E-plane at 12.7 GHz and 12.1 dB with 39 degrees at 15.0 GHz.
