摘要: Efficient small antennas are crucial in the development of wearable wireless communications and medical systems. Low efficiency is major disadvantage antennas. Meta materials technology active components used to improve Moreover, dynamic range communication system may be improved by using Amplifiers connected antenna feed line increase range. Novel wideband passive efficient metamaterial for IOT, BAN 5G applications presented this paper. The gain directivity with Split-ring resonators, SRR, higher 2.5dB than without SRR. resonant frequency SRR lower 4% 11% on human body shifted 3% 5%. Active receiving or transmitting For example, 13+3dB frequencies from 0.1GHz 0.8GHz. Noise Figure 0.5+0.3dB
