Embodiment Construction

[0030] The embodiment of the present invention provides a method and a mobile phone device for solving the HAC requirements of the mobile phone antenna. In order to make the purpose, technical solution and advantages of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] Antennas are complex devices, and the antenna embedded in the mobile terminal is no exception. Since the RF transceiver of the mobile terminal is designed for 50 ohm impedance, it is best for the antenna to present 50 ohm impedance in the entire frequency band. But in fact, this is difficult to do, because mobile terminal antennas are inherently characterized by narrow antenna bandwidth, poor matching, and low radiation efficiency. Therefor...

Abstract

The invention relates to the field of mobile communication and discloses a method for meeting the mobile phone antenna HAC demand and a mobile phone device. Due to integrated arrangement of an antenna matching circuit and an antenna radiating main body, an antenna radiating index can be switched from meeting normal performance to meeting HAC performance by only selectively starting a corresponding matching circuit. The current situation that the antenna main body or an antenna matching circuit on a mobile terminal circuit board needs to be redesigned so as to meet the antenna radiating HAC performance index. The method for meeting the mobile phone antenna HAC demand and the mobile phone device have the advantages of better guaranteeing the consistency of the antenna radiating HAC performance index and the mass production of an antenna mold and the matching circuit, reducing redevelopment time and development cost of the mobile terminal circuit board, reducing the control difficulty of circuit board materials, saving the cost and providing convenience for a user.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for solving the HAC requirement of a mobile phone antenna and a mobile phone device. Background technique [0002] When the wireless communication device works at the highest power state, it will cause serious electromagnetic interference to the surrounding electronic products, among which the interference is the most serious to the hearing aids used by the disabled, which will reduce the quality of the call. [0003] Therefore, according to this situation, in September 2006, the US FCC (Federal Communications Commission) enforced the HAC (Hearing Aid Compatibility mobile phone electromagnetic field interference limit on hearing aids for the hearing impaired) certification plan for mobile phone manufacturers. Its HAC reference The standard is ANSIC63.19 (the national standard method for measuring the compatibility of wireless communication equipment and hearing aids i...
