With proper mounting, a slot antenna can also be used for ‘microwave mobile’. With a 16-slot total, the antenna can have 10-12 dBi gain. Slot antennas can be built from surplus waveguide sections, which will give an omni-directional pattern and horizontal polarization. Design of dual-band and high gain waveguide slot antenna 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. 10 GHz waveguide slot antenna - OZ2OE

Babinet’s Principle | Waveguide Slot Antenna… Waveguide slot antennas are often used as omnidirectional microwave antennas. According to Watson4, the slot array was invented in 1943Figure 7-1 is a photograph of a typical waveguide slot antenna, with a total of 12 slots, six on each side, in WR-90 X-band waveguide for 10 GHz operation.
The final product only needs to be accurate to about 1mm as this will only shift the frequency within the range of the 802.11 spectrum. A smaller slot length will shift the frequency response of that slot to a higher channel. A longer slot length will shift it down. Changes in the slot spacing affects the vertical signal pattern.
