The radial line concentric slot array antenna - IEEE Conference ... The rotation mode feeding structure realized the concentric array radial line slot antenna for the bore sight beam. The axial ratio is 0.037dB. When the slot pairs ... Radial Line Slot Antennas - Springer
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

An eight-ring radial helical array antenna based on a novel slot-coupled structure is designed and simulated. The novel coupling structure has the advantages of high power-handling capacity and excellent coupling ability. The simulation results of the array antenna agree well with theoretical calculations, and the aperture efficiency is about 78.1% when the beam is in the normal direction. US Patent for Radial line slot array antenna 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. 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 frequency range is use for point to point microwave link.
