Using metamaterials in antenna design leads to interesting features includes size reduction. Although, the antenna miniaturization is the most promising advantage especially in commercial applications, their narrow band behavior causes great concern for the future progress. In this article, a near-field resonant parasitic (NFRP) antenna addressed. In order to increase the accuracy of antenna model in numerical simulations, a two-port model of the antenna suggested. Based on proposed model an accurate NIC loaded Non-Foster matching designed, simulated and fabricated. Measurement shows fractional bandwidth of about 4.75% from 268MHz to 280MHz. Due to the sensitivity of NIC circuits to their elements; a detailed parameter study also reported. This investigation clearly shows the antenna impedance response concerning whit the NIC circuit elements.
