Abstract: This paper presents an analysis of infinite phased arrays of aperture-coupled two-layer dual-patch microstrip antennas. The substrate layers for supporting the patches have the same dielectric constant and are separated by an airgap. The numerical model is based on the spectral-domain method of moments together with the Floquet theorem. Calculated results predicts a 2 :1 standing-wave ratio (SWR) bandwidth of 30-40% in a ±60C scan cone for arrays operating at around 4 GHz. Measured results from a waveguide simulator are obtained to verify the theoretical prediction. © 1996 IEEE.
