Abstract

In this paper, a new technique is proposed to analyse the mutual admittance between the slots of the radial line slot antennas (RLSA). No Green´s functions are required since the mutual and self admittance of the slot is obtained by computing the mutual impedance between the dipoles and their images due to the parallel plates. The number of the images to be computed for a desired accuracy are discussed while the mutual admittance of several kinds of slot arrangements are displayed.
