Abstract :
This paper proposes a different approach to non-Foster or active matching. An antenna structure with two ports is considered. One port is used to couple the signal, while the other one is connected to a non-Foster network. The advantage of this configuration is that the antenna can be designed to have real input impedance, as seen from the feeding port, fairly constant across a very broad band when the active load is applied. The input reactance compensation is essentially performed by the non-Foster network, typically behaving as a negative inductor.
