Radioengineering - April 2016, Volume 25, Number 1 [DOI: 10… The antenna structure is consist of a square radiation patch with an E-shaped slot, a modified ground plane with an inverted T-shaped strip that act as a parasitic stub and two parallel slots and a protruded strip which is connected to the … Radioengineering - June 2018, Volume 27, Number 2 [DOI: 10… From 7.9GHz to 12.1GHz, the antenna has an obvious gain enhancement, with a peak of 7dB, meanwhile, the antenna RCS is effectively reduced from 4GHz to 12GHz and the maximum RCS reduction reaches 25.4dB at 8.6GHz for x-polarized incident …

Abstract In mobile and satellite communications there is a need for low cost and low profile antennas which have a toroidal pattern. Antennas that have been developed for mobile communications include a L-Band electronically steered stripline phased array, a Ka-Band mechanically steered elliptical reflector antenna and a Ka-Band printed dipole.

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. IET Digital Library: Radial line slot array antenna with ... 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.

The Jampro JBCP‐H Optimizer High Power FM Antenna is designed for broadcast applications that require relative insensitivity to icing.

the antenna aperture in this case. A radial line slot antenna (RLSA) for surface-wave-coupled plasma (SWP) is a promising candidate to this end. A novel slot arrangement in the aperture, consisting of densely arrayed transverse slots, was fabricated and tested. Radial Line Slot Antenna Design for Monopulse Space Debris Radar 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
