  • Abstract
    Stability is the biggest problem in the matching of Electrically Small Antennas (ESAs) using non-Foster reactances realized by Negative Impedance Converters (NICs). However, it is not usually studied properly. In this paper we propose the Normalized Determinant Function (NDF) as a powerful method to test the stability of the systems formed by the NIC and the ESA, and we will show how conventional design can lead us to unstable solutions.
