A method for the analysis of infinite planar circular cylindrical phased arrays of waveguide fed apertures embedded in a lossy surface is presented. Use is made of the surface impedance concept and an appropriate equivalence principle to reduce considerably the number of simultaneous equations arising in the Galerkin procedure. Numerical results for the matched element gain pattern are presented for circular feed waveguides and compared with the lossless case.
