Abstract :
A high efficiency class AB power amplifier integrated with a modified microstrip patch antenna is reported. The second and third harmonics are tuned to obtain high efficiency operation The second harmonic is shaped through the input impedance of the patch antenna and third is tuned using a microstrip line with the periodically etched ground plane. A power-added efficiency of 61% is demonstrated at the operating frequency of 2.45GHz.
