Studies on the effect of mutual coupling on network and resonance properties of broad-wall longitudinal slot antenna

This paper presents, method of moments based analysis of a broad-wall longitudinal slot antennas in presence of another such antenna using Multiple Cavity Modeling Technique (MCMT). Theoretical data for reflection coefficient, transmission coefficient, resonance length and resonance conductance have been obtained. Due to the presence of second slot antenna there will be mutual coupling between them which in turn effect the network and resonance properties of such antenna. The theoretical data have been compared with Ansoft HFSS´s simulated data to validate the proposed method. The excellent agreement obtained between the results validates the analysis.
