Abstract

A broadband metamaterial-inspired antenna has been designed and tested numerically. By making full use of the space available in a planar, electrically small, near field resonant parasitic (NFRP) antenna, an internal non-Foster (active) circuit has been integrated into its NFPR element. Nearly complete matching of the whole antenna to 50 Ω has been achieved from 280.1 to 315.7 MHz without any matching network. The increased 10 dB bandwidth is more than 68 times the original value. The simulation results show that the radiation efficiency is above 78.5% over the entire 10 dB bandwidth range.
