Radial line slot array antenna

By Guest

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 ...

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.

A radial line slot antenna (RLSA) is a circularly polarized high efficiency planar array. Two types of RLSAs, a single-layered and a double-layered one, were released commercially for 12 GHz band direct broadcast satellite (DBS) reception. Radial line slot array (RLSA) antenna design for point to ... A new type of linearly polarized Radial Line Slot Array (RLSA) antenna developed by FR-4 substrate is proposed for outdoor WLAN point to point application. The WLAN is based on the IEEE 802.1 la standard and the operating frequency range is the upper UNII band (5.725-5.875) GHz. The development of radial line slot array antenna for direct ... An offset parabolic antenna design, which then eliminates the blockage, is susceptible to physical damage as its feed is significantly exposed from the body of reflector. 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 A Reconfigurable Radial Line Slot Array (RLSA) Antenna for ...
