A dual‐polarized L ‐band microstrip antenna was designed, constructed, and tested. A new design procedure based on optimizing the orthogonal mode isolation is demonstrated experimentally to provide highly decoupled feedlines and radiated fields with low cross‐polarization levels. Isolation between orthogonal ports of less than −36 dB across the operating band is reported. An impedance match of better than −10 dB over a 1% bandwidth centered around the resonant frequency was achieved. Cross‐polarization levels were less than −40 dB on boresight, and typically less than −35 dB over the entire radiated field on the resonant frequency. © 2000 John Wiley & Sons, Inc.
