2320MHz Slot antenna

2320MHz (13cm) Slotted waveguide Ant.
2320MHz (13cm) Slotted waveguide Ant.

Omnidirectional Sector Waveguide SLOT Antenna
C Band 2320MHz

The slotted waveguide has achieved most of its success when used in an omnidirectional role. It is the simplest way to get a real 10dB gain over 360 degrees of beamwidth

The Slotted waveguide antenna is a Horizontally Polarized type antenna, light in weight and weather proof.
3 Tuning screws are placed for tweaking the SWR and can be used to adjust the center frequency of your choice.

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.
Each of these slots allows a little of the energy to radiate. The slots are in a linear array pattern. The waveguide antenna transmits almost all of its energy at the horizon, usually exactly where we want it to go. Its exceptional directivity in the elevation plane gives it quite high power gain. Additionally, unlike vertical colinear antennas, the slotted waveguide transmits its energy using HORIZONTAL polarization, the best type for distance transmission !!
