A radial line slot antenna for an elliptical beam
A radial line slot antenna (RLSA) with a quasi-elliptical aperture to create an elliptical beam is discussed in this paper. A simple feeding structure consisting of a coaxial feeder and two parasitic pins is designed to produce the feed pattern required for uniform illumination over the aperture. ...
BEAM BROADENED RADIAL LINE SLOT ARRAY ANTENNA FOR FIFTH ... Radial line slot array antenna with broad beam is easily realized at frequencies in the lower part of super high frequency band. But emerging broadband mobile communication systems like the fifth generation target frequencies in the upper part of the band and beyond. Design of Non-uniform Aperture Illumination RLSA and Its ... Radial Line Slot Antenna (RLSA) is a well-known planar slot array antenna that provides high gain, high efficiency, low profile, and compact structure . Design of mm-Wave RLSAs with Lossy Waveguides by Slot ... This paper discusses how to design a Radial Line Slot Antenna (RLSA) whose waveguide is filled with high loss dielectric materials. We introduce a new design for the aperture slot coupling synthesis to restrain the dielectric losses and improve the antenna gain. Based on a newly defined slot coupling, a number of RLSAs with different sizes and loss factors are analyzed and their performances ... The Effects of Parasitic Superstrate Elliptical Shaped ...
Beam shaping is a challenging assignment for radial line slot antennas (RLSAs) which operate on oversized parallel plate waveguides. A RLSA for an elliptical beam with an elliptical aperture is designed and measured at 22GHz. Radiuses of the major and minor axes are 300mm and 150mm for an ellipticity of 2:1.

The authors present concentrically arrayed radial line slot array antenna for operation at 106 GHz. For compact design, they propose a vertical waveguide feeding with a cross-slot structure at the waveguide to cavity transition. Aperture design and optimisation are carried out using particle swarm optimisation with the goal to minimise the cross-polarised radiation.
