The wireless communications device includes a microstrip that has been structured to provide power to electrical circuitry and electrical components of the wireless communications device and has been adapted to transmit and to receive wirelessly a short-range wireless communications signal.
Claims23
A wireless communications device, comprising:
- a printed circuit board including electrical components;
- a power supply;
- a microstrip adapted to provide power to the electrical components of the printed circuit board and be a short-range communications antenna, wherein the microstrip is disposed on the printed circuit board and coupled to the power supply;
- and
- a cellular phone antenna.
A wireless communications device, comprising:
- a printed circuit board including electrical elements;
- a radio-frequency integrated circuit (RFIC) disposed on the printed circuit board;
- a compensation module coupled to the RFIC and including a tuning circuit;
- a trace disposed on at least one side of the printed circuit board and coupled to the compensation module, the trace providing power to the electrical elements of the printed circuit board, the trace being a short-range radio antenna,
- wherein the tuning circuit compensates for non-linear responses of the short-range radio antenna to radio-frequency signals;
- and
- a cellular antenna.
A short-range wireless communications device, comprising:
- electrical components;
- a microstrip adapted to be a short-range antenna and structured to provide power to the electrical components;
- a printed circuit board on which the electrical components are mounted;
- a power supply connected to the microstrip and providing power to the electrical components via the microstrip;
- and
- a cellular antenna.
A Bluetooth antenna in a handheld wireless communications device, comprising:
- a meandering power microstrip that has been adapted to radiate with a short-range omni-directional radiation pattern.
A method for short-range wireless communications, comprising the steps of:
- providing a wireless communications device comprising a printed circuit board, a microstrip disposed in a meandering pattern on the printed circuit board, a cellular antenna, and electrical components mounted onto the printed circuit board;
- providing power to electrical components of a wireless communications device via the microstrip;
- and
- transmitting or receiving short-range wireless signals via the microstrip.
A method for adapting a microstrip to be a Bluetooth antenna in a handheld wireless communications device, comprising the steps of:
- providing a printed circuit board adapted for electrical connection to a cellular antenna and to electrical components;
- printing a microstrip adapted to simultaneously provide power to the electrical components and act as a short-range communications antenna, wherein the mircrostrip is printed in a meandering pattern on a printed circuit board inside the handheld wireless communications device;
- impedance matching the microstrip with a Bluetooth integrated circuit;
- and
- compensating for non-linear responses of the microstrip to Bluetooth signals with a tuning circuit.
