In this paper, a negative-capacitance non-foster circuit (NFC) is designed to match an electrically small monopole antenna with a height of 300 mm. Since the effectiveness of an electrically small antenna is severely limited by gain-bandwidth theory due to high-Q impedances, a non-foster circuit is proposed to overcome this limitation. The proposed circuit is verified by using co-simulation based on HFSS and ADS, and the results indicate that the electrically small monopole antenna is well matched to the designed NFC with a bandwidth of 173% which ranges from 16 MHz- 222MHz.</p
