Abstract-In the higher frequency range, the wall-thickness causes more effects to the characteristic of slotted waveguide antenna. This paper presents numerical analysis of slotted waveguide antenna by incorporating the wall-thickness using finite element method for inner part of slot and boundary element method for outer or surface part. By using the field equivalent principle, the computation can be done only at the region of cut waveguide wall. The solution of those methods are employed to calculate the electric field along the slot surface and further use to calculate the equivalent network parameters of slot antenna. The results show the agreement to the published numerical and measurement results in the references.

Abstract-An inclined semi-circular slot cut in the narrow wall of a rectangular waveguide has been analyzed. By enforcing the boundary condition of continuity of the tangential magnetic field at the slot aperture, an integral equation with the aperture electric field as the unknown has been obtained and solved by the method of moments (MoM). The equivalent slot admittance is then determined. Different slot parameters, such as scattering coefficients, normalized resonant conductance, resonant length versus tilt angle, and radiation patterns, have been studied. The results obtained by the MoM have been verified by comparing them against those results obtained with HFSS.

Microwave components, antennas, and systems that meet the tight requirements of today's advanced wireless terrestrial and satellite‐based communication systems—in particular concerning increased specifications and performance—demandfastEM‐based computer‐aided design (CAD) tools yielding accurate, highly optimized components within adequately short design times. This goal makes flexible and efficient hybrid solutions desirable, which typically go beyond the design capabilities of the involved single methods. The chapter presents an overview of the state of the art of hybrid CAD mode‐matching (MM)/finite‐element (FE)/method‐of‐moments (MoM) techniques applied for the rigorous, fast CAD and optimization of waveguide components, antennas and arrays and describes recent advances. The hybrid techniques presented combine advantageously the efficiency of the MM method with the flexibility of the FE method and the efficiency and flexibility of MoM for radiating structures. Typical application examples illustrate the versatility and high efficiency of these hybrid techniques.
