Abstract

A method and wireless communication device use a first processing unit to perform a first communication event within a first communication window by use of a first communication protocol, a second processing unit to perform a second communication event within a second communication window by use of a second communication protocol, and a wireless communication unit connected to a radio-frequency antenna to transmit and/or receive a packet wirelessly. The first and second processing units may perform the first and second communication events via the wireless communication unit. The second processing unit or the wireless communication unit may transmit an event signal to the first processing unit when performing the second communication event or receiving a packet, respectively, to allow the first processing unit to arrange the first communication window (or first communication event) with respect to the second communication window (or second communication event) to minimize interference.

First claim

7. The wireless communication device of claim 1 , wherein the wireless communication device is wearable on an ear of a user.

8. The wireless communication device of claim 1 , wherein the wireless communication device is a hearing aid.

9. The wireless communication device of claim 1 , wherein the wireless communication device has a length of between 4 cm and 12 cm.

10. The wireless communication device of claim 1 , wherein an electrical length of the first antenna element is one of:
λ/4;

x*λ/ 4+λ/2; and

x*λ/ 4−λ/2;

wherein x is an odd number ≥3.

11. The wireless communication device of claim 1 , wherein the single radio-frequency antenna operates within a frequency range of 2.4 to 5.5 GHz.

12. The wireless communication device of claim 1 , wherein the first antenna element is arranged at the end of the single radio-frequency antenna.

13. The wireless communication device of claim 1 , wherein a distance between points where the second and third antenna elements are respectively connected to the first antenna element is determined according to a current or voltage distribution along the first antenna element.

14. The wireless communication device of claim 1 , wherein one end of the first antenna element is connected to a ground plane via the second antenna element, the second antenna element extending along a second side of the single radio-frequency antenna substantially perpendicular to a first side.

15. The wireless communication device of claim 1 , wherein, at a point between respective ends of the first antenna element, the third antenna element connects the first antenna element to a current feeding unit, the third antenna element extending from the first antenna element to the current feeding unit in a direction substantially parallel to a side of the single radio-frequency antenna, the current feeding unit being configured to provide a current to the first antenna element via the third antenna element.

16. The wireless communication device of claim 1 , wherein the wireless communication device is configured as an intermediary device facilitating wireless communication between a mobile phone and a hearing device.
