Abstract

The need for small antennas with wide instantaneous bandwidth is well established in mobile Cognitive radio nodes or transceivers. The fundamental limit of small antennas is a problem which passive matching cannot solve. However, non-Foster matching provides a means of getting around this problem. In this paper, we show a negative impedance converter that provides a negative capacitor up to 1.5GHz and we show how it can be used to match a small chassis antenna. This improves the instantaneous bandwidth of the antenna beyond what is achievable with passive matching.
