Abstract :
A moment method analysis is used to calculate the current distribution on a linearly tapered slot antenna. The surface current distribution is computed for several test cases. The results for an antenna with L/ lambda =5.2, W/ lambda =2.5, and 2 gamma =14 degrees are shown. Radiation pattern results are in good agreement with experimental data.<>
