Abstract

The present disclosure relates to impedance tuning of transmitting and receiving antennas.

Claims (18)

1. A device comprising:

a transceiver;

a receiving antenna;

a transmitting antenna;

a receiving branch coupled between the transceiver and the receiving antenna, the receiving branch including a receiving tuning circuit and a first filter, and wherein the receiving tuning circuit matches an impedance of the receiving narrowband antenna with an impedance of a receiving amplifier and further matches the impedance of the receiving antenna with an impedance of the first filter;

a transmitting branch coupled between the transceiver and the transmitting antenna, the transmitting branch including a transmitting tuning circuit, wherein the transmitting tuning circuit matches an impedance of the transmitting antenna with an impedance of a transmitting amplifier;

a control unit to determine the impedance of the receiving amplifier and the impedance of the transmitting amplifier.

2. The device of claim 1 , wherein the transmitting branch further includes a second filter, and the transmitting tuning circuit further matches the impedance of the transmitting antenna with an impedance of the second filter.

3. The device of claim 1 , wherein the receiving amplifier and the transmitting amplifier are included in the transceiver.

4. The device of claim 1 , wherein the receiving amplifier is included in the receiving branch and the transmitting amplifier is included in the transmitting branch.

5. The device of claim 1 , wherein the receiving antenna, the transmitting antenna, or a combination thereof, are a planar inverted F antenna (PIFA).

6. The device of claim 1 , wherein the transmitting antenna, the receiving antenna, or a combination thereof, have a building height less than or equal to 1 millimeter.

7. The device of claim 1 , wherein the receiving tuning circuit matches impedances of the receiving antenna with the impedance of a receiving amplifier across a plurality of frequency ranges, wherein each frequency range is associated with a receiving band of a different wireless communication technology.

8. The device of claim 1 , wherein the transmitting tuning circuit matches impedances of the transmitting antenna with the impedance of the transmitting amplifier across a plurality of frequency ranges, wherein each frequency range is associated with a transmitting band of a different wireless communication technology.

9. The device of claim 1 , wherein the transmitting antenna includes one or more tuning elements to match an impedance of the narrowband antenna with the impedance of the receiving amplifier.

10. The device of claim 1 , wherein the transmitting antenna includes one or more tuning elements to match an impedance of the transmitting antenna with the impedance of the transmitting amplifier.

11. The device of claim 1 , wherein the transmitting tuning circuit matches impedances of the transmitting antenna with impedances of a plurality of filters across a plurality of frequency ranges.

12. The device of claim 1 , wherein the receiving tuning circuit matches impedances of the receiving antenna with impedances of a plurality of filters across a plurality of frequency ranges.
