Abstract :
This paper presents an analysis and design of a negative impedance converter (NIC) circuit for wideband matching of an electrically small antenna operating in the receive mode, and that stability work condition is also given. Experimental results presented demonstrate that the active receiving antenna exhibits good voltage gain and signal-to-noise ratio and that the active antenna is stable.
