Radial line s lo t array antenna at 28 GHz with modified Radial line slot array antenna (RLSA) is a low loss planar antenna which has ease of manufacture and possess attributes like high efficiency and gain [1]. It can be designed for linear [2] or circular [3], [4] polarization. It attracted attention in applications such as wireless LANs [5], local multiport Radial Microstrip Slotline Feed Network for Circular steered microstrip array [2], a L-Band microstrip phased array tracking antenna for mounting on a car roof [3] and a X-Band radial line slotted waveguide antenna [4] have been demonstrated. In the above electronically scanned printed arrays [1] and [3], the individual element radiates normally to the plane of the array and hence require a phase BANDWIDTH ENHANCED AND SIDELOBES LEVEL REDUCED …
Abstract: A planar linearly polarized radial line slot array (RLSA) antenna is proposed to achieve a high gain with improved impedance matching and suppressed cross-polarization levels at a 270-GHz band. The proposed antenna is integrated in low-temperature cofired ceramic (LTCC).
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 Radial Line Concentric Slot Array Antenna of the antenna is the radial line waveguide0slot array antennas. This structure are made from two plate for radiating waveguide. In this research, based on the theoretical calculation of the hybrid feed structure composed of the circular waveguide and coaxial feed and ring slot, and patch structure and the radial line.

RLSA(Radial line slot antenna) is slotted waveguide array antenna which is proposed for the DBS(Direct Broadcast from a Satellite) reception. Theoretically, it has lower conduction loss and higher effectiveness than the planar antenna using microstrip. DL-RLSA(Double-layered RLSA) uses radially inward travelling wave
