高效的小型天线在可穿戴无线通信和医疗系统的发展中至关重要。效率低是小型天线的主要缺点。利用超材料和分形技术来提高小型天线的效率带宽。此外，使用有源可穿戴天线可以提高通信系统的动态范围和效率。可将放大器连接到可穿戴天线馈线，以增加系统动态范围。提出了一种面向物联网、宽带宽带和5G应用的新型宽带无源和有源高效可穿戴天线。带开口环谐振器的贴片天线的增益和方向性比不带分裂环谐振器的贴片天线高2.5dB。有SRR的天线的谐振频率比没有SRR的天线低5%~10%。有源小型可穿戴天线可用于接收或发送通信、物联网和医疗系统。例如，在1.25 GHz到3.25 GHz的频率范围内，有源缝隙天线的增益为12±2dB。在1 GHz~3.3 GHz频率范围内，有源缝隙天线的噪声系数为0.6±0.2分贝。
Efficient small antennas are crucial in the development of wearable wireless communications and medical systems. Low efficiency is the major disadvantage of small antennas. Meta material and fractal technology are used to improve the efficiency bandwidth of small antennas. Moreover, the dynamic range and the efficiency of communication system may be improved by using active wearable antennas. Amplifiers may be connected to the wearable antenna feed line to increase the system dynamic range. Novel wideband passive and active efficient wearable antennas for IOT, BAN and 5G applications are presented in this paper. The gain and directivity of the patch antenna with Split-ring resonators, SRR, is higher by 2.5dB than the patch antenna without SRR. The resonant frequency of the antennas with SRR is lower by 5% to 10% than the antennas without SRR. Active small wearable antennas may be used in receiving or transmitting communication, IOT and medical systems. For example, the active slot antenna gain is 12±2dB for frequencies from 1.25GHz to 3.25GHz. The active slot antenna Noise Figure is 0.6±0.2dB for frequencies ranging from 1GHz to 3.3GHz.
