Antenna structures and methods thereof for adjusting an operating frequency range of an antenna

摘要

A system that incorporates the subject disclosure may include, for example, a circuit for obtaining a desired bandwidth of operation of the antenna structure, adjusting a bandwidth of the antenna to achieve the desired bandwidth of operation of the antenna structure, and tuning the antenna to a new resonant frequency to accommodate transmitting or receiving RF signals at a desired band of operation. The antenna at the new resonant frequency is at least approximately at the desired bandwidth of operation of the antenna structure. Other embodiments are disclosed.

主权项

1. A method, comprising:
responsive to a first determination that interband carrier aggregation is not necessary, adjusting, by a circuit comprising a processor and an antenna, a reactive element of the antenna to reduce an operating bandwidth of the antenna and to reduce desensitization due to transmission outside a passband of the antenna; responsive to a second determination that intraband carrier aggregation is necessary, adjusting, by the circuit, the reactive element of the antenna to increase the operating bandwidth of the antenna; and tuning, by the circuit, the antenna to a new resonant frequency to accommodate transmitting or receiving RF signals at a desired band of operation, wherein the antenna at the new resonant frequency has the reduced or increased operating bandwidth of the antenna.
