Abstract

Monitoring system with Bluetooth low energy (BLE) beacons is promising for position identification of elderly wanderers. BLE beacons can be mounted in shoes for convenience, and a shoe-mounted directional antenna is expected to efficiently radiate the beacon signals to the data server of the monitoring system. In this paper, a directional array antenna with planar or curved structure was designed on the shoe surface for this purpose. The antenna was designed to sweep diagonally upward from 10° to 50°, and the simulated and measured S11 performances revealed reasonable agreement. The antenna was assumed to be used in an urban environment, and a directional patch array antenna with dielectric lens was also designed to receive beacon signals by mounting it on utility poles. According to a feasibility experiment result of elderly wanderer position identification, the designed directional antenna can provide an almost 100% position identification rate if a wanderer is within 20 m from a smart phone user.
