Saad, “Reconfigurable Radial Line Slot Array microstrip patch antenna with random and unsymmetrical slots (RLSA) Antenna for Beam Shape And Broad-Side are presented in this paper. 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. (PDF) Elliptical Shaped Antenna With Parasitic Superstrate ... Keywords-elliptical patch antenna; parasitic superstrate; The paper is organized as follows: In section 2, the detailed design of the antenna will be explained ranging from the elliptical design, the slots, and the connection between slots, the cylindrical patches and the dimensions of the ground the antenna consists of dielectric FR4 with an ...
3. Results for Radial Line Slot Antennas The source reconstruction technique has been applied to the simulated and the measured data of a K-band radial line slot antenna (RLSA) shown in Fig. 3 and the designed magnetic current at each slot. The RLSA consists of 1062 slots, and operates at 19.9 GHz.
BANDWIDTH ENHANCED AND SIDELOBES LEVEL REDUCED RADIAL LINE ... Also, it can be designed for circular, linear or elliptical polarization. But achieving a reduced sidelobes level has not been an easy task in its design. This paper presents a simple technique to improve the impedance bandwidth and reduce the sidelobes level in linearly polarized Radial Line Slot Array Antenna at 28 GHz for 5G mobile ken-system: Fundamental Research of Radial Line Slot ... 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. Radial Microstrip Slotline Feed Network for Circular ...

A reconfigurable radial line slot array (RLSA) antenna for ... A reconfigurable beam shape and broadside radiation pattern microstrip antenna is introduced in this paper. The antenna's radiating surface is designed using a radial line slot array (RLSA) arrangement, which is fed from an aperture coupled structure. Radial Line Slot Antenna Simulation - YouTube
Radial Line Slot Antenna Design for Monopulse Space Debris ...
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 ... Radial line slot array antenna - NEC Space Technologies, Ltd.
