In human life, healthcare is a major aspect, so it should be considered for every people. Because, every people required high quality of life. The population of new born babies and elderly age peoples moderately increased in the world. Today many elderly peoples are stay alone at home, due to high-priced healthcare facilities such as nursing home/hospitals and high cost of health service monitoring technology. To overcome this issue, introducing a remote health service monitoring technology through telehealth application at low cost. The healthcare monitoring system depends on wearable antenna and modern communication and information technology. These technologies allow elderly people to stay alone at home instead of expensive hospitals/nursing homes. The NWCFs technology is suitable for wearable antennas fabrication and closed hand shape logo introduced on patch. The human physiological signals such as HR, BP, EDA, ECG, EMG, and RR are measured by using wearable antenna. The 5G technology is preferred for transmitting the wearable antenna measured data. The 5G technology includes sub-6 GHz frequency band and it has three ranges: 3.3-4.2 GHz, 3.3-3.8 GHz, and 4.4-5.0 GHz. The NWCFs based wearable antennas are flexible, easy to fabricate, easy to washable and have low price. The NWCFs based designed antenna CST results are compared with HFSS simulative results and measured results. The antenna performance with size reduction and without size reduction techniques also discussed.
