A rigorous full-wave analysis in the spectral domain\ud for trapezoidal patch antennas is presented in this paper. Particularly,\ud a new set of entire domain basis functions for an efficient\ud implementation of the method of moments (MoM) is carried out\ud by properly imposing the boundary conditions. The simulated results\ud obtained through the presented method are compared to the\ud measurements showing a good agreement. Finally, a parametric\ud analysis of the main antenna features (matching, radiation pattern,\ud cross-polarization levels) is also carried out

Slot-loaded trapezoidal patch antennas are analyzed\ud in order to achieve a multifrequency operation. A moment\ud method formulation based on new analytical entire domain basis\ud functions is developed and compared to the one involving the\ud RWG triangular discretization. The numerical results obtained\ud through the new efficient implemented code are compared to the\ud measurements showing a good agreement. A parametric analysis\ud of such antennas is also presented leading to useful design graphs\ud showing the main antenna properties (resonance frequencies,\ud cross-polarization levels, matching, etc.) as a function of the patch\ud geometrical dimensions, symmetric collocation of the slots on the\ud patch, and slot dimensions
