A Miniaturized Multi-band Omnidirectional Antenna for Medical Healthcare Monitoring

Here a miniaturized broadband omnidirectional antenna has been designed using traditional elliptical shape microstrip patch antenna integrated with corrugated metal-insulator-metal (MIM) plasmonic structure for electromagnetic compatibility measurement. Numerical simulations verified that the antenna has multi-band and wide-band with a small size of 0.24λ*0.24λ (76mm*76mm). Such compacted broadband and multi-band omnidirectional antenna is necessary for smart healthcare system, which can find many applications in various areas including remote medical monitoring, wearable devices, implantable devices and so on.
