Limitations and Metrics for Non-Foster Matching of Electrically-Small Transmit Antennas

Abstract

The proposed research aims to study the limitations of ideal and practical non-Foster circuits for electrically-small transmit antennas. Specifically, we will investigate the bandwidth barriers of a non-Foster circuit with regard to impedance, power handling capability, transmission efficiency, power efficiency, and the non-linearity of the elements. We will perform simulations and calculations of ideal non-Foster circuits (e.g., –C and/or –L) to examine the theoretical upper bound of bandwidth (Task 1), whereas parametric sweeps and machine learning algorithms will be employed to generate a massive amount of realistic non-Foster circuits to trace the practical performance bounds of the fundamental parameters.
