Wire Grid Modeling of the Linear Tapered Slot Antenna

Abstract

The linearly Tapered Slot Antenna (LTSA) has been the subject of considerable study and experimentation. Accurate theoretical models base on the Method of moments (MOM) have been developed to study the radiation characteristics of this antenna. however, these models are limited due to the great amount of Central Processing Unit (CPU) time required to obtain the solution. Employing the Numerical Electromagnetics Code (NEC) an accurate wire- grid model of the LTSA is developed here in order to reduce the CPU time needed to obtain the solution. Numerical results are presented for the radiation pattern and compared with experimental results of the actual planar structure to validate the model and optimize the wire-grid. Once the model has been optimized, effects of variable design parameters on radiation pattern are studied. Conclusions are made regarding optimum designs for the LTSA. Theses.
