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 flat, radial line slot antenna having a radial waveguide including a front plate and a rear plate, the front plate being provided with an array of radiating slots formed therein and an array of reflection cancelling slots formed in the rear plate, wherein the radiating slots in … IET Digital Library: Radial line slot array antenna with
