An active integrated antenna (AIA) which consists of a T‐shaped microstrip‐line‐fed slot antenna is proposed. Since the designed antenna has an electromagnetically coupled feedback loop, it can easily solve the problem of DC isolation between a radiator and amplifier. The fabricated parallel‐feedback antenna oscillator shows stable oscillation at a frequency of 10.05 GHz. The measured effective isotropic radiated power (EIRP) is 37.79 mW, and the cross‐polarization levels are at least −15‐dB lower than those of co‐polarization for all directions. © 2005 Wiley Periodicals, Inc.
