Slot antenna design - ResearchGate All Answers ( 5) It is probaby a good idea to build and test some slot antennas to get a feeling for how they work. Of course, an analysis using CST,HFSS, FEKO, COMSOL is also a good idea. Please refer to the paper "Improving Radio Performance in Wireless Applications Using Slot Antennas" by Gerardo Gonzalez Wireless Design Magazine Jun 09, pp. (PDF) A single-layer SIW slot array antenna with TE20 mode The idea of using higher order modes is demonstrated by an SIW slot array antenna with a TE20 mode to realize boresight radiation.
The older RSGB VHF-UHF Manual, the one by Jessop, has several skeleton slot antennas described in it. Now the skeleton slot uses vertical rods for the basic antenna rather than a cylinder as in the one you describe. However, the principle is the same and they are an effective antenna. Glen, K9STH
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). The polarization of the slot antenna is linear. Basic Slot Antenna and Its Complementary Dipole - Neets 3-17 Basic Slot Antenna and Its Complementary Dipole The slot antenna consists of a radiator formed by cutting a narrow slot in a large metal surface. Such an antenna is shown in figure 3-18. The slot length is a half wavelength at the desired frequency and the width is a small fraction of a wavelength. Slot antenna - Wikipedia 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. Antenna Theory - Slot - Tutorials Point Slot Antenna is an example of Aperture antenna. A rectangular slot is made on the conducting sheet. These slot antennas can be formed by simply making a cut on the surface, where they are mounted on. The use of slot antennas is well understood through its working principle. Let us have a look at the ...
In recent years, printed slot antennas are under consideration for use in UWB applications and are getting more and more popular because of theA square slot antenna excited by a CPW-fed widened tuning stub was proposed in [17]. By properly choosing the location and size of the tuning stub, the...

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, as shown in Figure 6.16, is considered another basic radiating element.It is realized by removing a small area of metal from an infinite ground plane. For a practical design, however, the ground plane may be finite but large in size.

A New Method for the Design of Slot Antenna Arrays: Theory ... propose optimization-based algorithms for slot antenna arrays [7]. These methods, however, are too complicated and appear to be cumbersome to realize. The basic idea in Elliot [3], [6] was to consider each half-wavelength waveguide section with one slot as a basic “slot module” with variable load impedance attached to it.
