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.
radial line slot antenna at 94 GHz for space debris detection. The paper has included the optimization process the calculation of the antenna gain through different efficiencies. Finally, a feeding network based on 4+1 pins is selected. The central pin generates the difference beam, while the four US Patent for Radial line slot antenna Patent (Patent ... A flat radial line slot antenna having a radial waveguide is disclosed. The antenna has a front plate and a rear plate, the front plate having an array of radiating slots and an array of reflection cancelling slots formed in the rear plate. US9214740B2 - Radial line slot array antenna - Google Patents A radial line slot array antenna in general has a plurality of slots arranged to fit a specific frequency (central frequency of used frequency band), and hence has a problem that the usable frequency band is narrow. The radial line slot array antenna described in Patent Literature 2 is intended to solve the aforementioned problem. A Radial Line Slot Antenna for an Elliptical Beam - IEEE ...
A microstrip antenna is disclosed which comprises a ground conductor plate and a patch opposed to the ground conductor plate with a particular distance, a transmission feed line and a reception feed line being disposed between the ground …

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.

Despite what someone else said about the Hustler 5BTV, I bought one two months ago and installed it without radials. My first two contacts were Europe and I snagged Moldova out of a huge pileup two nights ago running only 100 watts into this antenna on 20 meters.
Antenna Basics - A transmitter needs an antenna to send its radio signal, and a receiver needs an antenna to pick up that radio signal. The simplest form of antenna is the...
An antenna providing circular polarization for received and transmitted signals. The antenna comprises a vertical conductive surfaces oriented to form a closed structure and horizontal conductive surfaces forming a top face of the closed …
