Aug 14, 2015 · Design and Implementation of RSLA Antenna for Mobile DBS Application in Ku-Band. • This antenna is implemented with brass as conductor and air (er ≈ 1) as dielectric material and has eight concentric array slot pairs to achieve conical beam, better gain and wider frequency bandwith compared to Makoto Ando model. Radial line slot array antenna - NEC Space Technologies, Ltd. Dec 15, 2015 · A radial line slot array antenna has a slotted conductor plate in which a plurality of slots are formed and arranged in a spiral. The plurality of slots are arranged in the slotted conductor plate such that the arrangement distance in a radial direction between the slots varies gradually between a first portion determined based on a first frequency and a second portion determined based on a Multilayered Cavity Material Radial Line Slot Array Khan, 2011)) are being considered. At millimeter wave band, microstrip antenna design becomes challenging and to date little is known about antenna design at millimeter wave for cellular or mobile communication (Chen & Zhang, 2013). Radial Line Slot Array (RLSA) antenna with its starling characteristic of high gain, low cost, US Patent for Radial line slot antenna Patent (Patent

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 32GHz RLSA antenna is adaptive Cartesian FDTD simulated for Radiation Pattern. Design of Elliptical Microstrip Antenna for Ultra Wide Band ... Fig.1: Front View of Antenna In the present paper, an elliptical microstrip patch antenna for Ultra Wide Band applications has been designed. We are using elliptical patch because it provides comparatively larger bandwidth than others. Fig.2: Bottom View of Antenna The partial ground plane method is used in this antenna, Radial line slot array antenna - NEC Space Technologies, Ltd.

Radial Line Slot Antenna Design for Monopulse Space Debris 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 ken-system: Fundamental Research of Radial Line Slot
