摘要： A communication device includes a ground element, an antenna element, a circuit element group, and a communication module. The antenna element is a loop antenna. One end of the antenna element is a grounding end coupled to the ground element, and the other end of the antenna element is a feeding end close to the grounding end. The circuit element group includes at least two separate circuit element sub-groups. The communication module is coupled to the circuit element group. One of the circuit element sub-groups of the circuit element group is selectively coupled to the feeding end so as to make the antenna element operate in different communication bands.

摘要： An electronic device may have tunable antenna structures. A tunable antenna may have an antenna resonating element and an antenna ground. An adjustable electronic component such as an adjustable capacitor, adjustable inductor, or adjustable phase-shift element may be used in tuning the antenna. An impedance matching circuit may be coupled between the tunable antenna and a radio-frequency transceiver. The adjustable electronic component may be coupled to the antenna resonating element or other structures in the antenna or may form part of the impedance matching circuit, a transmission line, a parasitic antenna element, or other antenna structures. During manufacturing, manufacturing variations may cause the performance of the tunable antenna to deviate from desired specifications. Calibration operations may be performed to identify compensating adjustments to be made with the adjustable electronic component. Calibration data for the adjustable component may be stored in control circuitry in the electronic device.
