Abstract

Abstract

In this paper, a new type of high-gain circular polarized backfire antenna is presented. It is developed on the basis of equivalent reflector method proposed by the author (1979, 1981). A eircular polarized wave is obtained by use of two orthogonal dipoles. The lengths of the two dipoles are so chosen that the real parts of their input admittances differ in 90. The transverse dimension of the antenna is 2.24, the axial dimension is 2, the weight of the complete antenna assembly is only 1.2 kg. The gain measured is 17.5dB, the axial ratio is 0.5 dB, VSWR is 1.18 at centre frequency.
