Prototypes development for reflection canceling slot design ... Abstract: A radial line slot array (RLSA) antenna is a high gain and high efficiency planar antenna which is suitable for direct broadcast satellite (DBS) reception. The satellite communication market commonly uses the standard parabolic dish antenna. However, the use of this type of antenna has some disadvantages. US Patent for Radial line slot array antenna Patent (Patent ... A radial line slot array antenna in general has a plurality of slots arranged to fit a specific frequency (central frequency of used frequency band), and hence has a problem that the usable frequency band is narrow. The radial line slot array antenna described in Patent Literature 2 is intended to solve the aforementioned problem. Multilayered Cavity Material Radial Line Slot Array Antenna ... 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, A reconfigurable radial line slot array (RLSA) antenna for ...

LPRLSAA. (redirected from Linearly-Polarized Radial Line Slot-Array Antenna). Acronym. A Radial Line Slot Array (RLSA) Antenna with the… It is recommended by several researches that RLSA antennas have possibility as an option for Wi-Fi devices antennas. Therefore, to dig deeper thisThe measurement results are quite agrees with the simulation results. We found that with the same size of 0.05 m2, our RLSA antennas has better... Analysis of a high power microwave radial line slot … A traditional radial line slot antenna (RLSA) is a high gain planar array. To improve the power handling capacity, we design a radial line slow wave structure which replaces a traditional dielectric sheet in the radial waveguide of the traditional RLSA. This high power microwave (HPM) RLSA is fed... Antenna Arrays | Linear Phase Progression Between…

US9214740B2 - Radial line slot array antenna - Google Patents 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 ... The development of radial line slot array antenna for ... The radial line slot array (RLSA) type antenna is thus designed to cope with the problems encountered in parabolic antennas. RLSA is a planar antenna suitable for direct broadcast satellite (DBS) reception, with advantages including high radiation efficiency (high gain), low profile, low cost and feed rear-mounted. 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. This novel feeding structure for an RLSA antenna incorporates PIN diode switches which are integrated with the feed line structure to enable the ...
