Abstract

The invention discloses an antenna and terminal equipment for CMMB (China mobile multimedia broadcasting), and is used for receiving CMMB signals. The CMMB antenna comprises a terminal equipment metal frame which is used for receiving CMMB signals, and an antenna circuit which is connected with the metal frame and used for processing the CMMB signals, so that the CMMB signals can be played on the terminal equipment. According to the technical scheme of the invention, the CMMB antenna can complete high-sensitivity CMMB signal reception without arranging an external rod antenna or a built-in CMMB antenna; the material cost of the CMMB antenna is saved as the existing structure of the terminal equipment is used.

Description

technical field [0001] The invention relates to the field of electronic products, in particular to a CMMB antenna and terminal equipment. Background technique [0002] At present, most mobile phone TV antennas are designed with external rod antennas, and some built-in TV antennas use ceramic antennas or FPC antennas, but these antennas need to be combined with special low-noise amplifier modules, and the product design costs are relatively high. The scheme needs to divide and select the CMMB frequency band to solve the problem of the narrow bandwidth of the CMMB built-in antenna, but the antenna design system is complex, the debugging difficulty and design cost are high, which is not conducive to the performance optimization design and mass production of the antenna . [0003] Therefore, the CMMB antenna in the prior art has the problems of low product performance and high production cost. Contents of the invention [0004] The invention provides a CMMB antenna and termi...
