Most of the medical applications of antennas involve coupling electromagnetic energy into the human body or into other biological systems, such as animals used in experimental measurements. Primarily, these applications can be divided into two categories: therapy and diagnostics.
Multiple wireless protocols are used for Medical IoT:
● Cellular, both broadband (5G-ready, Sub-6, 600-6000 MHz) & narrowband (NB-IoT)
● WiFi, including single-band 2.4 GHz applications, dual-band 2.4 & 5 GHz & the new WiFi 6e band up to 7.2 GHz
● RFID, tracking the location of the devices themselves or contents removals from storage areas
● ISM, and other low power wireless networks (LPWAN) such LoRaWAN® & Sigfox
● Land Mobile Radio, traditional 2-way communications on VHF or UHF
