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.
For the compact antenna design, a single-layered radial line slot antenna (RLSA) utilizes a radially outward traveling wave, and the slot length is varied to synthesize uniform aperture illumination. The DBS reception antenna consists of back plate, foam, slotted plate, and radome as shown in Fig. 1. The radial line is terminated by a matching ...

Taub NASA Lewis Research Center, Mail Stop 54-5 21000 Brookpark Road, Cleveland, Ohio 44135 INTRODUCTION In mobile and satellite communications there is a need for low cost and low profile antennas which Design of a slot-coupled radial line helical array 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.
