Flexible 2.4 GHz node for body area networks with a compact high-gain planar antenna
Flexible 2.4 GHz node for body area networks with a compact high-gain planar antenna
A flexible 2.4 GHz wireless sensor node with a bespoke single layer monopole antenna, tuned for on-body operation for wearable applications, is presented. Multiple antenna design approaches for tuning on-body antennas have been investigated. The proposed antennas, patch and meandered,designed for operation in the insole, exhibit a simulated realised gain of -3.98 dB and -1.97 dB respectively. The antennas were fabricated on a 25 μm flexible polyimide substrate, exhibiting up to 16% lower insertion losses at 20 GHz than FR4 PCBs. The integrated node incorporates a commercial Bluetooth Low Energy(BLE) system-on-chip and exhibits 9 dB higher measured gain than commercial modules with reference antenna design.Moreover, through functional radio test, it was confirmed that the designed node passes Bluetooth transmitter certification tests.

Abstract
A flexible 2.4 GHz wireless sensor node with a bespoke single layer monopole antenna, tuned for on-body operation for wearable applications, is presented. Multiple antenna design approaches for tuning on-body antennas have been investigated. The proposed antennas, patch and meandered,designed for operation in the insole, exhibit a simulated realised gain of -3.98 dB and -1.97 dB respectively. The antennas were fabricated on a 25 μm flexible polyimide substrate, exhibiting up to 16% lower insertion losses at 20 GHz than FR4 PCBs. The integrated node incorporates a commercial Bluetooth Low Energy(BLE) system-on-chip and exhibits 9 dB higher measured gain than commercial modules with reference antenna design.Moreover, through functional radio test, it was confirmed that the designed node passes Bluetooth transmitter certification tests.
