Abstract To solve the contradiction between the high gain and wide coverage, the concept of the quasi‐conical beam is proposed by using the high‐gain pencil beam electrically switching along a cone to make full use of time redundancy. In a periph

Abstract A novel loop antenna is proposed here. This antenna uses an annular arm made of pure water to take the place of the metallic loop of a typical loop antenna. The water arm is enclosed by a resin loop tube. The arm has circular cross section t

A novel sum and difference (SD) conical beam-scanning reflector antenna is proposed in this paper. The reflector surface, illuminated by two omnidirectional horns, is a body of revolution obtained by revolving the generating parabola about a symmetry
