Abstract :
The cross antenna is a medium gain and circular polarization structure made of a conductor or strip line over a ground plane, following a cross contour of four or more branches. One end is feed by a generator and the other one is charged with a load impedance. This paper presents a theoretical and experimental analysis of an eight arms cross antenna, loaded with four different impedances. The theoretical study is made via the computational solution of Pocklington´s equation applied to the structure; experimental results are obtained over an antenna of a 12 AWG wire over a ground plane, working in 3.2 GHz. We present radiation efficiency, gain, field pattern, and axial rate results
