Rf Front-end Technologies Based on Active Integrated Antennas and Pbg

چکیده
In this paper, we present novel design architectures that use either a periodic structure or an active integrated antenna (AIA) for harmonic tuning in transmitter front-end designs. These techniques promise to significantly improve the power amplifier efficiency, reduce losses and weight, as well as maintaining good linearity. We will illustrate these two concepts through several design examples that have been developed recently, including a power amplifier integrated with novel PBG ground plane for harmonic tuning and a push-pull PA design example. Additionally, an active retrodirective antenna array is presented to illustrate the flexibility of active front-end technologies.
