A linearly polarized radial line slot antenna - IEEE Abstract: A design for linearly polarized radial line slot antenna (RLSA) is proposed. A novel slot arrangement is presented which couples to the rotationally symmetric guided waves to produce a uniform aperture distribution with linear polarization. Basic characteristics were measured in the 12-GHz band on a model antenna. Radial line slot array (RLSA) antenna design for point to
A radial line slot array antenna is presented and experimentally discussed for a fifth generation (5G) mobile communication system that resonates at the frequency of 28 GHz. Additionally, it is low profile, simple structure, easy to manufacture with high gain and radiation characteristics.
E-mail: ksudo@antenna.ee.titech.ac.jp 1 Introduction A radial line slot antenna (RLSA) was a high gain, high efficiency and low-cost planar antenna, which was conventionally proposed for DBS reception at 12 GHz band [1]. In the conventional RLSA, a radial waveguide was fed by a coaxial feeder. In millimeter wave band, Prototypes development for reflection canceling slot design ... A more beneficial design is that of the radial line slot array (RLSA) type antenna. Advantages of this antenna include its high radiation efficiency, low profile, low cost and rear-mounted feed. The prototype development starts with the selection of the cavity's dielectric material and construction of the coaxial-to-waveguide transition.
