摘要：

A new integrated antenna power amplifier architecture is investigated. In this topology, a multifeed patch antenna is used as the tuned load of a class-B push-pull amplifier in such a manner that the fundamental radiates efficiently and higher harmonics are suppressed. This eliminates the necessity of using a second hybrid at the output of the amplifier and results in an extremely compact class of push-pull front end with lower associated circuit losses. Measured data shows that the power-added efficiency of the amplifier is greater than 55%, indicating that this new approach works as expected.
