摘要

In this paper, a low frequency ultra-wideband electrically small monopole antenna (ESMA) with a non-foster circuit (NFC) loading for HF/VHF application is proposed. The devised ESMA has a very small height of 30 cm at 18 MHz, whose performance is severely limited due to the electrically small size characterized by large reactance and small radiation resistance. To conquer the limitation of the passive matching method, a NFC is developed and properly designed to cancel out the large reactance of ESMA and broaden the bandwidth. In this paper, the design principle is presented in detail for devising an ESMA system. At last, circuit and electromagnetism co-simulation is constructed to make the results more accurate and convinced. The simulated and measured results indicate that a -10 dB fractional bandwidth of 169% ranging from 18 MHz to 218 MHz is obtained for the designed ESMA matched by the NFC.
