The present invention is a wireless device for monitoring human body activity comprising a wearing piece suitable to be worn on a human body. Inside the wireless device there is a central data processing unit 10 which comprises at least one sensor 101, a data storage device 102 and a wireless communication device 103. The wireless communication device is specifically a Bluetooth Low Energy (BLE) device. The data storage device is connected with the sensor and temporarily stores data detected by the sensor. The wireless communication device is connected with the data storage device and configured to communicate with an external data processing device 20 for further processing. The present invention also comprises a power source 30 which connects with and supplies power to the central data processing unit. In preferred embodiments the wireless communication device includes a differential dipole patch antenna (4, figure 3) which comprises a substrate (41, figure 3), a grounding plate on one side of the substrate, two radiating components (42, figure 3) arranged in mirror symmetry each of which forms an arm with a bending or meandering structure, a differential feed end (43, figure 3) comprising two micro strip lines which are connected to the radiating components and a further microstrip line (44, figure 3) connecting the two radiating components. |
