Abstract: This paper deals with extending bandwidth of electrically small antenna using negative impedance converter that acts as a negative reactance.
Using the idea of negative impedance converter an active reactance circuit is proposed to cancel the imaginary part of electrically small antenna impedance and thus matched antenna to the transmitter over a wide band. Furthermore, design and measurement results of active reactance circuit are presented and discussed in details.
