A linearly polarized traveling‐wave microstrip array antenna is parallel and series fed by microstrip transmission lines. Excellent antenna efficiency is achieved by having proper impedance matching throughout the array and by properly utilizing the reflected power from the end of the array. Very low cross‐polarization radiation is achieved by exciting the patches and transmission lines with antiphase technique.
