A Beam Steering Radial Line Slot Array (RLSA) Antenna with ...

Hence Radial Line Slot Array (RLSA) antenna which has inherent narrow beam characteristics becomes a potential candidate antenna for this application. The use of RLSA for microwave and millimeter wave application is not totally a recent idea as reported by Albani et al [3]. Research on RLSA started in the early Radial line s lo t array antenna at 28 GHz with modified coaxial... 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 Reflection coefficient calculation of a feeder structure in a ... Indexing Terms : Radial Line Slot Antenna, Direct Broadcast from a Satellite, Tilting Rod 1. Introduction RLSA(Radial line slot antenna) for the DBS(Direct Broadcast from a Satellite) reception in the 12GHz band is in commercial use in Japan. Its flat shape is so solid and so small compared with the planar antenna using microstrip. Radial line slot array (RLSA) antenna design for point to ...

Radial Line Slot Antennas - Home - Springer Radial Line Slot Antennas Hiroyuki Arai* Yokohama National University, Yokohama, Kanagawa, Japan Abstract This chapter presents the development history of radial line slot antenna. The antennas are used for circular polarized high-gain antenna in microwave and millimeter wave bands. Linearly polarized arrays A reflection cancelling slot set in a linearly polarized ... Abstract: A radial line slot antenna (RLSA) is a high-gain and high-efficiency planar antenna. A linearly polarized RLSA (LP-RLSA) is attractive for applications of various subscriber radio systems. However, the slot arrangement for linear polarization gives rise to serious reflection from slots, which disturbs the normal antenna operation. Radial Line Slot Antennas | SpringerLink 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. RLSA - What does RLSA stand for?

Radial Line Slot Antenna (RLSA) [1] is an attractive candidate for high gain and low cost circular polarized antennas. During the last decades, there has been an increasing interest in RLSA due to several reasons: the first of them is their simple structure, which makes them suitable for low cost mass production. Radial line slot array (RLSA) antenna design for point to point...

A radial line slot antenna (RLSA) is a slotted waveguide planar array proposed for DBS subscriber antennas. Predicted conductor loss of RLSA is almost negligible. A single-layered RLSA (SL-RLSA) has the simplest structure. A Concise Design of Large mm-Wave Radial Line Slot Antenna ... This paper reviews the state of the art concise design of a large aperture Radial Line Slot Antenna (RLSA) in millimeter waves to be used as a satellite on-board antenna. Honeycomb structures are employed as core of the dielectric spacer to reduce the antenna’s weight. We derived an equivalent model for the design and analysis of large Characteristics of small-aperture, single-layered, radial ... A radial-line slot antenna (RLSA) is a high-efficiency planar array. A double-layered radial line and uniform slot length have been adopted in conventional RLSAs. A single-layered RLSA is much simpler in structure, but the slot length must be varied to synthesise uniform aperture illumination.
