A center‐fed reflect‐array antenna with nonuniform substrate as a reflecting surface is proposed. To design and analyze this kind of antennas, a simple method based on an equivalent circuit model is introduced. Using this method a low cross‐polarization of about −21 dB below the main beam peak and wide 3‐dB gain bandwidth of 19.5% are obtained at X‐band frequency. © 2012 Wiley Periodicals, Inc.
