Abstract :
A simple but accurate method is presented to predict the radiation pattern of a single layer Radial Line Slot Array (RLSA) antenna. In this method, radiating slots are replaced by equivalent magnetic dipoles for which excitation coefficients are obtained by employing a small-coupling theory to the coaxial-probe-launched TEM radial mode. Comparison between theoretical and experimental results for 55 cm diameter RLSA antennas show that the presented method of predicting the radiation pattern works well
