Abstract

The invention relates to a frequency-reconfigured built-in antenna, comprising an antenna stand (13), antenna patterns (14) on the antenna stand and connectors of the antenna patterns, wherein the connectors are electrically connected with a circuit board; the antenna patterns are monopole antenna patterns of which two ends are respectively connected with respective connector; the connector at one end is electrically connected with a feeding terminal on the circuit board, and the connector at the other end is sequentially connected with a gating switch (16) on the circuit board as well as a short-circuit arm and a grounding elastic sheet for regulating frequency on the circuit board. According to the frequency-reconfigured built-in antenna, one antenna pattern can work under a monopole or loop-circuit antenna mode by controlling the gating switch; and the frequency-reconfigured built-in antenna can meet the multi-band working requirement of a handheld device, is simple and compact in structure, and can greatly save antenna space.

Description

technical field

[0001] The invention relates to wireless communication, in particular to a frequency reconfigurable built-in antenna, especially applicable to dual-mode or multi-mode mobile phones. Background technique

[0002] With the rapid development of information technology, more and more information subsystems are installed on the same wireless communication system, and the increase of information subsystems will inevitably lead to the increase of antenna frequency band and complexity. Looking at the wireless communication market, the thinning and miniaturization of handheld terminals The trend of thinner and smaller miniaturization will inevitably lead to smaller and smaller design space reserved for antennas. Many existing built-in antennas use multiple antenna patterns to meet different frequency requirements. Therefore, although they have multiple frequency bands, these antennas require a large space. How to design multi-frequency band antennas in a limited antenn...
