Abstract

The invention discloses a signal processing method and electronic equipment. The method comprises steps of receiving a first instruction, wherein the first instruction is an instruction for indicating support of a second frequency range, and the center frequency of the second frequency range is different from that of a first frequency range; and responding to the first instruction, and controlling a resonance unit for adjusting self impedance, so that an antenna unit is enabled to resonate with the center frequency of the second frequency range, wherein the self impedance of the resonance unit presents inductance characteristics. The invention can support the antenna unit for working at multiple frequency ranges, and the radiation performance of the antenna unit at each frequency range is ensured.

Description

technical field [0001] The invention relates to communication technology, in particular to a signal processing method and electronic equipment. Background technique [0002] When the antenna environment in electronic equipment cannot meet the requirements of conventional antenna design, the common solution in the related art is to use a switch to switch the matching circuit to support different frequency bands, or use an adjustable capacitor to switch different frequency bands , to achieve the purpose of electronic equipment supporting broadband. [0003] However, the final performance of the antenna mainly depends on the standing wave ratio of the antenna (that is, the degree of matching) and the inherent radiation performance of the antenna. In the related art, the standing wave ratio of the antenna is often emphasized, and the radiation performance of the antenna is ignored, resulting in weak radiation performance of the antenna when realizing a wide frequency band of th...
