Here, we present the development of a high-gain omnidirectional ring-based SWAA based on a circular waveguide
, as presented in Figure 2.
Among his topics are phased array antennas, wideband impedance matching of a V-dipole antenna, lumped-element impedance matched antennas, a circular waveguide
antenna for a portable computer-based radar, a three-dimensional printed non-planar circular patch array antenna, and antenna and electromagnetic field measurements.
These antennas consist of identical inclined slots placed on a circular waveguide
and two radially outward parallel cylindrical plates in order to provide circular polarization.

This method was developed some decades ago and has been applied to classical waveguides with analytic modal spectrum such as the rectangular waveguide, the circular waveguide
, and the elliptical waveguide for many types of waveguide devices such as transformers, filters, and couplers [7-11].

According to conventional resonant frequency formulas of metallic circular waveguide
resonators, the corresponding resonant frequency of [TM.sub.11] in the hexagonal cavity can be determined by modified formulas as follows:
We compare our numerical results with the well-known exact solution for the circular waveguide
obtained by the method of separation of variables (see, e.g., ).
In this paper, the UTD method is utilized to calculate the farzone amplitude patterns in the E and H planes, and to examine the impact of the square and circular ground plane edges on the amplitude patterns of a conical horn, and rectangular and circular waveguide
The generation of high order modes in circular waveguide
is useful for some applications.
