A fast frequency‐sweep technique is presented for the analysis of cavity‐backed microstrip patch antennas. This technique applies the method of asymptotic waveform evaluation (AWE) to the hybrid finite‐element boundary‐integral (FE–BI) solution of the original boundary‐value problem. Numerical examples show that the proposed technique can speed up the analysis by more than an order of magnitude. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 22: 389–393, 1999
