Abstract :
An X-band active integrated antenna push-pull power amplifier is presented that uses a dual feed microstrip leaky-wave antenna for both out-of-phase power combining and second harmonic tuning. This novel structure results in a compact and high efficiency power amplifier design. At the operating frequency of 8.7 GHz. A maximum measured PAE of 54% at an output power of 38.1 dBm has been achieved
