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.
