System and methods for adaptive antenna optimization

摘要

A method (600) and devices for enhancing the performance of one or more antennas (440) is provided. A control circuit (104) assesses performance of an antenna (101) in a plurality of bands, such as a receive band and a transmit band. The control circuit (104) then selects one of the bands, e.g., a lesser performing band, as a “selected band” for which the antenna (101) will be optimized. The control circuit (104) can then adjust an adjustable impedance matching circuit (103) coupled to the antenna (101) to improve the efficiency of the antenna (101) in the selected band and can adjust a resonance of the antenna (101) to further improve an efficiency of the antenna (101) in the selected band.

1. A method of optimizing performance of an antenna system in a wireless communication device operating in multiple bands, the antenna system comprising at least one radiating element, the method comprising:
assessing performance of the antenna system in one or more of a receive band and a transmit band; selecting one of the receive band or the transmit band as a selected band for which the antenna system will be optimized based upon assessed performance; altering a resonance of the at least one radiating element to improve an efficiency of the antenna system in the selected band; and adjusting an impedance matching circuit coupled to the at least one radiating element to further improve the efficiency of the antenna system in the selected band; wherein the selectin depends upon at least one of the following:
which of the receive band or the transmit band has a lesser link margin;an antenna bandwidth margin, a data throughput margin, power indicia received from a remote base station, or a data latency margin; ora form factor configuration of the wireless communication device, an orientation of a user's hands on the wireless communication device, a physical orientation of the wireless communication device, or combinations thereof.
