CHAPTER 2 DESIGN AND MODELING OF EXPONENTIALLY TAPERED SLOT ANTENNA 2.1 ... as the ground plane for the antenna and the antenna is fed by a balanced slot line. However, drawbacks for a planar TSA come in the form of using a low dielectric constant substrate and obtaining an impedance match for the slot line. RESONANT LENGTH CALCULATION AND RADIATION PATTERN SYNTHESIS OF ... Method of Moments (MoM) technique. Resonant length calculation of the slot is a critical parameter in the design of waveguide slot array antenna. All computed results are compared with simulated results. CST Microwavestudio is used for the simulation and is totally based on FIT techniques. For computation purpose MATLAB 7.0 is used. The numerical data on transmission and reflection coefficient are evaluated. Method of moment solution is used to calculate resonant length versus slot offset ... A high-gain and high-bandwidth waveguide fed longitudinal slot doublets ... In this paper Method of Moment, based Multiple Cavity Modelling Technique (MCMT) is used for analysis of a high-gain and high-bandwidth waveguide longitudinal slot doublets array antenna.

Moment Method Analysis of Slot Coupled Waveguides of longitudinal slots. The rst attempt of using a moment method technique on the slot problem was done by Khac and Carson [3, 4], where they derived an integral equation for the electric eld just at the slot aperture, from which the total elds in the structure could be calculated thanks to the Schelkuno equivalence principle. Moment method analysis of linearly tapered slot antennas An accurate Method of Moments (MoM) model is developed and implemented for the analysis of the linearly tapered slot antenna (LTSA). The model employs an unequal size reactangular sectioning for conducting parts of the antenna. Piecewise sinusoidal basis functions are used for the expansion of conductor current.

Modal expansion method is also applied to slot coupled microstrip antennas in [4]. Input impedance calculation of slot coupled microstrip antennas using transmission line modeling is presented in [5], [6]. They also show good agreement with the measured results. Thirdly, moment method analysis of this antenna is explained in TAPERED MEANDER SLOT AND COPLANAR SLOT ANTENNA FOR DUAL AND ...
