摘要
Non-Foster reactive elements are embedded inside compact resonant antennas, rather than being employed in matching networks located at the antenna terminals. These embedded non-Foster elements interact with the inherent Foster reactances of the antenna, resulting in a broadband antenna with a high radiation resistance. The class of suitable antennas for this application is discussed, a design procedure is presented and a sensitivity and a stability analysis are performed. Finally, experimental results for a representative non-Foster antenna are presented and discussed.
