The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications. 12 Slot Waveguide Antenna for 2.4GHz - YouTube In this video I build a 2.4GHz waveguide out of aluminium tubing. The methods of construction are much the same as the smaller 5.8GHz slot but I also go over... 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. TechTalk#101 - DATV - Looking at a “Slot” Antenna for 1.2 GHz

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. below 6cm slot antenna 20 slots 14.7 dbi 125 euro ... - PE1RKI 10ghz slot antennas are 125 euro, i used to sell them for 150 euro but i noticed i had competition in this area so i lowered price. 10ghz and 24ghz can have waveguide or sma input. Many of my antennas are now on repeaters and beacons in many europe countries. below 6cm slot antenna 20 slots 14.7 dbi 125 euro a piece. closeup A High-gain and Low-scattering Waveguide Slot Antenna of ...
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.

Simulated impedance bandwidth is from 5.58 GHz to 5.82 GHz with S11 < –10 dB for the proposed antenna and from 5.48 GHz to 5.86 GHz for the common antenna. The slight difference between the common antenna and the antenna with metamaterial array is attributed to the cou- 10 GHz waveguide slot antenna - OZ2OE
