Compact Patch Antenna for Wearable Health Monitoring Applications

Ashwini Kumar Arya

Abstract: This paper presents a design study of a compact antenna for the wearable devices. Bluetooth Low Energy (BLE)/2.4 GHz frequency has been considered for the wearable device and communications. The proposed antenna is designed on 0.2 mm thick FR4 substrate with ?r = 4.4 and tan?= 0.02. The proposed antenna along with the 80 MHz bandwidth centered at 2.45 GHz results an expected omnidirectional radiation performance in horizontal plane and its suitability to be installed inside the wearable device above to the sensors integrated PCB circuitry on the top cover of the smart wearables. The antenna structure is a compact patch antenna configuration with the inset feeding structure and shorting at another end. With the aim at the usages in the abovementioned scenario (inside the device along with the circuit PCB considerations), the flexibility and the performance of the antenna element is well suitable for the wearable devices.
