A novel metric wave ultra-wideband plasma antenna based on monopole with parasitic elements

A metric wave ultra-wideband plasma antenna based on monopole with parasitic elements is proposed in this paper. The antenna is designed with operation frequency 40-110MHz using the plasma antenna technology and top-loaded technology. According to the simulation results, the antenna with well low-elevation performance has a 93% relative bandwidth with return loss less than -10dB and omnidirectional radiation pattern in horizon plane. It can be used broadly in the military and civilian fields for its good structure and electrical characteristics.
