Abstract :
A general expression is proposed for the coupling of surface wave antennas based on the equivalence principle and on the reciprocity theorem. A particular application is presented for disc-on-rod antennas, and the coupling coefficient is evaluated as a function of frequency, the array parameters and the element parameters. A physical explanation of the results is suggested.
