The function of row wireless signal transmission is so that the quality of radio communication can obtain certain guarantee.
But, in realizing process of the present invention, inventor finds that in prior art, at least there are the following problems: if user
Carry out conversing and mobile phone close to the number of people time because international regulations, such as FCC (Federal Communications
Commission, FCC) with CE (Communicate European, European commission), human body is inhaled
Receive radiant power SAR (Specific Absorption Ratio, specific absorption rate) to disturb with to human body sonifer, such as FCC's
((Hearing Aid Compatibility, hearing aid compatibility) has the restriction specification of upper limit threshold to HAC, so situation is often
Must by systems soft ware drive decline plate end input antenna conducted power arrive meet SAR Yu HAC test specification and
Impact on human body.But, the now performance of antenna efficiency, including launching and receiving frequency range, as make close to the number of people
Become deterioration, that is radio communication quality can decline again.
Affect the degree of Consumer's Experience for avoiding communication quality to drop to, often diversity antenna or the auxiliary antenna of top needs
Ensure that certain space, for preferably radiating, therefore, also results in product size relatively big, and makes product competitiveness glide.Again
Person, some chip judges after not supporting to switch antenna whether mobile phone reduces the function of conducted power on number of people side.In these feelings
Under shape, use the mobile phone of these chips the most often close because of being tested by SAR above it (but not limiting top) point
The function that collection antenna or auxiliary antenna are launched, consequently, it is possible to when the main antenna of lower section is because being held by user and performance declines to a great extent
Time, performance for wireless communications, especially emitting portion just provide without other and improve or the mechanism remedied and pipeline, and makes Consumer's Experience
The most often can therefore and substantially deteriorate.
