This paper presents an active integrated antenna with a dual-feeding push-pull patch. Two oscillators were mutually synchronized by symmetry of the push-pull patch with oddmode excitation. The oscillator was designed using the maximum loaded oscillator method. The single patch antenna was oscillated at 5.48 GHz. The mesured directivity was in good agreement with the desired pattern. The E-plane two-element array was fabricated and measured. The two-element array antenna was oscillated at 5.13 GHz with even-mode operation.
