Make Slotted Waveguide Omni Antenna

make slotted waveguide omni antenna

Make a high-gain, horizontally polarized omni or unidirectional antenna that looks cool. Unlike wideband antennas such as the Biquad [Hack #88], slotted waveguides are resonant antennas and have a relatively narrow operating frequency range.

for array antennas with a small number of slots (N≤ 12). In an extreme situation mutual coupling can lead to an antenna physical non-realizability, which was studied in [10]. In this paper a design method of a slotted waveguide antenna with longitudinal slots cut in a broad waveguide wall is proposed. In the presented method the internal

So, a folded rectangular slotted waveguide antenna made out of 30 resonant slots on the broad wall of the guide in the form of a ring has provided a perfect omnidirectional pattern with an average gain of 15 dB. The maximum size of this antenna does not exceed 60 cm in diameter and 6cm in height when placed horizontally.

In this paper, a new waveguide slotted antenna array, in which T-shaped cross section waveguide is used as the radiating waveguide, is proposed and simulated. The T shaped radiating waveguide can reduce the waveguide profile height. The radiating slots are etched and inclined alternately on the top [1, 2, 3].

What we used was 1 x 32 slot (15db 360 degree omni) waveguide and 1 x 16 slot (16db 180 degree omni) waveguide. 32 slot waveguide antenna These were connected to Enterasys wireless cards directly using the short pigtail adapter. We then set about finding a location where we had clear line-of-sight (LOS) over a large distance at ground level.


This radiating slot array antenna is made out of a printed circuit sandwich structure with: a radiating plate in printed circuit form transparent to microwaves having, on its upper face, a metallization plane in which there are etched alignments of radiating slots; chutes made of a plastic material with a metallized inner wall, the chutes having their hollow part before the upper face of the ...

A slot antenna has a generally cylindrical waveguide and a feed end. A plurality of slots are formed in the waveguide. A plurality of feed strips are secured to the feed end and are secured to the waveguide in spaced apart relationship from the outer surface of the waveguide. Exciters are in communication with the feed strips and extend over the slots.

The waveguide itself acts as a transmission line, and the slots in the waveguide can be viewed as parallel (shunt) admittances. The end of the waveguide is short circuited, so a rough circuit model of Figure 1 is: Figure 2. Circuit model of slotted waveguide antenna. The last slot is a distance d from the end (which is short-circuited, as seen ...

Slot antenna - Wikipedia

Hight does improve wifi signals, thats why you tend to find antennas up on poles or on antenna towers. The issue of corrogated iron is a problem though but its worth trying an antenna on the roof of your house, a good one. I recommend employing a 16 slot waveguide omni antenna which will pump out about 16dbi. $124.

How a Slotted Waveguide Antenna Works This antenna, called A slotted waveguide, is a very low loss transmission line. It allows to propagate signals to a number of smaller antennas (slots). The signal is coupled into the waveguide with a simple coaxial probe, and as it travels along the guide it traverses the slots.

Slot antennas are popular omnidirectional microwave antennas. These antennas feature omnidirectional gain around the azimuth with horizontal polarization. Waveguide slot antennas, usually with an array of slots for higher gain like Figure 7-1, are used at frequencies from 2 to 24 GHz, while simple slotted-cylinder antennas like Figure
