This paper presents CAD based analysis of a proposed high gain, broad band nearly omnidirectional waveguide broad-wall longitudinal slot array antenna. Ansys HFSS has been used to simulate the structure. A 36 element slot array antenna has been simulated, fabricated and tested. The fabricated antenna provides a high gain and nearly omnidirectional radiation pattern over large band width.
This paper presents, method of moments based analysis of dual slot coupled broad wall slot coupler using Multiple Cavity Modeling Technique (MCMT). Theoretical data for reflection coefficients and transmission coefficients have been obtained. Due to the presence of slots there will be internal mutual coupling between them which has been taken into account. The theoretical data have been compared with...

In this paper we have presented a moment method analysis of a shunt - series slot fed waveguide broad wall shunt slot radiator. To analyze the circuit Multiple Cavity Modelling Technique (MCMT) has been used. The theory has been validated by the excellent agreement obtained between the MCMT and Ansoft HFSS simulated data.
In this paper an attempt has been made to analyze waveguide circuits for non-sinusoidal, periodic excitations. The excitation functions, taken as example, are trapezoidal and clipped sine wave in nature and the waveguide circuit, that has been considered, is two interacting thick inductive irises. The excitation functions have been expressed in terms of Fourier series. The circuit has been analyzed...
