Abstract
The present disclosure relates to wireless communication device antennas with tuning elements.
Claims20
A wireless communication device comprising:
- a transceiver;
- and
- a narrowband antenna including one or more tuning elements to match an impedance of a transmitting amplifier, the impedance of a receiving amplifier, or a combination thereof, with an impedance of the narrowband antenna, wherein the one or more tuning elements change a resonance frequency of the narrowband antenna.
A device comprising:
- a transceiver;
- a narrowband antenna;
- and
- a tuning circuit, wherein a first node of the tuning circuit is coupled to a transmitting amplifier, and wherein the tuning circuit matches an impedance of the narrowband antenna with an impedance of the transmitting amplifier.
1 more element
A method comprising:
- determining, by a wireless communication device, absorption loss of a first narrowband antenna, the first narrowband antenna including a plurality of tuning elements to match an impedance of the first narrowband antenna with an impedance of a transmitting amplifier of the wireless communication device, an impedance of a receiving amplifier of the wireless communication device, or a combination thereof;
- determining, by the wireless communication device, absorption loss of a second narrowband antenna, the second narrowband antenna including a plurality of tuning elements to match an impedance of the second narrowband antenna with an impedance of the transmitting amplifier, the impedance of the receiving amplifier, or a combination thereof;
- determining, by the wireless communication device, whether the absorption loss of the second narrowband antenna is greater than the absorption loss of the first narrowband antenna;
- transmitting signals, by the wireless communication device, via the first narrowband antenna when the absorption loss of the second narrowband antenna is greater than the absorption loss of the first narrowband antenna;
- and
- transmitting signals, by the wireless communication device, via the second narrowband antenna when the absorption loss of the second narrowband antenna is less than the absorption loss of the second narrowband antenna.
