In this paper, we propose a new waveguide slot array configuration, in which the slots are printed on a copper-clad substrate. This configuration can be obtained using a printed slot and therefore allows both a simpler realization of a slot array and permits its reuse when the pattern requirement changes. An innovative and highly effective method of moments procedure has been devised. It employs a spectral domain approach for the computation of the internal Green function. Our code has been validated against a commercial finite element method code, and the agreement is highly satisfactory. The code has then been used to obtain the scattering and radiating properties of the proposed printed slot. Such a slot behaves as a shunt admittance, so Elliott's method (1983) can be used to design an array of printed slots.

Abstract
In this paper, we propose a new waveguide slot array configuration, in which the slots are printed on a copper-clad substrate. This configuration can be obtained using a printed slot and therefore allows both a simpler realization of a slot array and permits its reuse when the pattern requirement changes. An innovative and highly effective method of moments procedure has been devised. It employs a spectral domain approach for the computation of the internal Green function. Our code has been validated against a commercial finite element method code, and the agreement is highly satisfactory. The code has then been used to obtain the scattering and radiating properties of the proposed printed slot. Such a slot behaves as a shunt admittance, so Elliott's method (1983) can be used to design an array of printed slots.
