patterns are obtained with different excitations of the radial line slot antenna (RLSA). Basically, if the slots are placed in concentric rings, when the RLSA is excited in the centre, a conical or difference beam is generated. However, if a rotating mode is excited, a pencil or sum beam is generated. This 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.

A Beam Steering Radial Line Slot Array (RLSA) Antenna with ... A beam steering radial line slot array (RLSA) antenna with reconfigurable operating frequency is proposed in this paper. The RLSA antenna is fed by an aperture coupled structure, which incorporates PIN diode switches that are integrated with the feed line. It is found that the beam steering ability and reconfigurable operating frequency are greatly influenced by the spiral and radius of feed ... BANDWIDTH ENHANCED AND SIDELOBES LEVEL REDUCED RADIAL LINE ... design of narrow beam antenna with an appreciable reduced level of sidelobes and sufficient bandwidth is paramount for 5G operation. Hence Radial Line Slot Array (RLSA) antenna which has inherent narrow beam characteristics becomes a potential candidate antenna for this application. The use of RLSA for microwave and millimeter TEL Release TriasTM SPA Plasma Processing System Capable ... Based on the Radial Line Slot Antenna (RLSA) microwave plasma developed for semiconductor processes by Professor Tadahiro Ohmi at Tohoku University, the Trias SPA uses the unique Slot Plane Antenna (SPA) plasma generating technology established by TEL, after long years of cultivating plasma technology.

We proposed a resonant-tunneling-diode (RTD) terahertz (THz) oscillator for circularly polarized radiation, which is convenient for THz wireless communication. The oscillator is composed of an RTD, a cross-slot resonator, and a radial line slot antenna (RLSA). The output of the RTD in the cross-slot

The radial line slot antenna (RLSA) is a paral- lel plate slot antenna, which was proposed as a pencil beam antenna for DBS reception in 12 GHz band [2], [3].
E-mail: ksudo@antenna.ee.titech.ac.jp 1 Introduction A radial line slot antenna (RLSA) was a high gain, high efficiency and low-cost planar antenna, which was conventionally proposed for DBS reception at 12 GHz band [1]. In the conventional RLSA, a radial waveguide was fed by a coaxial feeder. In millimeter wave band, RLSA - Definition by AcronymFinder
