N2 - This work presents our preliminary work on an electric field (E-field) prediction technique and near-field tofar-field transformation of a surface wave antenna with a cosecant-squared pattern for a millimeter-wave FMCW vertical-looking radar system. Fourier and Gaussian fitting models were used to predict the magnitude and phase of E-field on the antenna surface, and the prediction error at the center operating frequency of 34.5 GHz are 4.6% and 4.6° respectively. The far-field E-plane pattern was achieved by applying Fourier Transform to the predicted near-field E-field distribution.
