Basic idea of slot antenna

By Author

I'm building a bumper mounted antenna tower, EMT with some square tube. Earlier today I stumbled across an article on 2 meter slot antennas cut in to satellite dishes. Literature is repetitive either directed towards that subject or TV and UHF broadcasting. I like the idea of a Dipole analogue that doesn't look like an antenna...

A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots cut out. When the plate is driven as an antenna by a driving frequency, the slot radiates electromagnetic waves in a way similar to a dipole antenna. The shape and size of the slot, as well as the driving frequency, determine the radiation pattern.

Basic Slot Antenna and Its Complementary Dipole

The Basic Antenna and how it Works. An antenna can be defined as any wire, or conductor, that carries a pulsing or alternating current.Gain: An antenna that radiates poorly has low “gain”. Antenna gain is a measure of how strongly the antenna radiates compared to a reference antenna...

US6057802A - Trimmed foursquare antenna radiating element

Slot Antenna Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). Cavity-Backed Slot Antennas - Antenna Theory A practical slot antenna is the cavity-backed slot antenna. Unfortunately, the equations related to the cavity backed slot antenna are somewhat complicated and in my opinion don't give a good idea of how they work. Hence, I'll present the basics, present some experimental results and try to give an idea of design parameters.
