Title: Broadband matching of small antennas using negative impedance converters
Abstract: Small antennas with wide instantaneous bandwidth are vital in mobile Cognitive radio nodes or transceivers. The fundamental limit of small antennas is a problem which passive matching cannot solve. Non-Foster matching provides a solution to this problem. In this paper, we show a negative impedance converter that provides a negative capacitor up to 1.5GHz and use it to match a small chassis antenna. This improves the Q of the antenna beyond what is achievable with passive matching.
