Abstract
A traveling-wave feeder type coaxial slot antenna, comprising: a central conductor extending over a certain length; a cylindrical outer conductor coaxially surrounding the central conductor; and a plurality of slots provided in the outer conductor at a certain inclination angle, for instance 45 degrees, relative to a longitudinal axis of the outer conductor. This antenna can be conveniently fabricated from a commercially available coaxial cable. By suitable selection of the inclination angle of the slots and their mutual spacing, the antenna may be provided with a directivity directed to a desired elevation angle when mounted on a vertical wall to make is suitable for receiving radio wave signals from a satellite.
