Wave Propagation Analysis of a Millimeter-Wave Slotted Metallic Waveguide Feed Technique with MOM-GEC Method

The importance of the millimeter wave spectrum has significantly grown with the launch of the 5G. To utilize the millimeter wave spectrum of 5G efficiently, suitable feeding techniques of microstrip antenna are a natural requirement. In this context, we propose to ensure a comparative study of the wave propagation of a Slotted Waveguide operating in high-frequencies according to boundary conditions applied on the Waveguide walls. The originality of this work is to ensure the electromagnetic study based on the hybridization of the Generalized Equivalent Circuits Method (MGEC) with the Method of Moments (MOM) which is considered among the most interesting integral methods to apply for the study of the electromagnetic aspect on planar structures. In fact, we have proved through this Method that the rise in frequency is accompanied by the existence of propagation losses effects which are justified by the intrinsic impedance applied on the walls of the waveguide that must be taken into account for the Feed Technique Analysis. Numerical results are presented and show a good agreement when compared with HFSS Software.
