Description

A kind of antenna for mobile telephone set
Technical field
The utility model relates to wireless communication technology, particularly a kind of antenna for mobile telephone set.
Background technology
Mobile phone is typical small-sized wireless communication equipment.Because the restriction of mobile phone size, make the application of antenna in mobile phone usually occur the improvement of a lot of needs in, such as, the problem that ECC (envelope correlation coefficient) is low not and HAC (hearing aid compatibility) is high not of beam formed antenna, mimo antenna can not be well applied to.
Specifically, about the problem being applied to beam formed antenna, in order to adapt to the size of mobile phone, beam formed antenna being used in mobile phone, needing the direction changing radiation diagram main beam.The conventional solution of antenna for mobile phone makes it have omnidirectional radiation diagram.But above-mentioned antenna does not have optimum performance in radiation, and reason has: what omnidirectional radiation diagram was subject to that user holds has a strong impact on; Energy is omnidirectional to be radiate, not only towards base station, also towards the direction obtaining best throughput as far as possible.Antenna for mobile telephone set of the present utility model allows the radiation diagram reinventing or revise antenna for mobile phone, and makes it re-start orientation towards specific direction.

In order to make MIMO (multiple-input and multiple-output) antenna system have good performance, each antenna must by separately certain distance, the wavelength of this distance corresponding to given frequency.The distance of correlation between the signal received by each antenna normally and between antenna is inversely proportional to.In order to obtain good MIMO performance, low correlation, namely between antenna, need the distance that large.This means, be applied to the mimo antenna in radio communication mobile device, because the small size of portable equipment and the task of facing the challenge property, especially in the low-frequency band lower than 1GHz.
About the problem that HAC is not high enough, the loud speaker of mobile phone and/or the sound quality of hearing aids can significantly reduce because Electric and magnetic fields is coupled from mobile phone antenna to mobile phone and/or the audio system of hearing aids.In order to ensure certain tonequality, this field coupling needs are reduced.Loud speaker can be arranged in the low current region on the PCB of mobile phone usually.But due to the restriction of handset size size, the current value on the low current region on mobile phone PCB of the prior art is still comparatively large, and can not be effectively reduced or eliminate, and thus its HAC is lower.
At present, in prior art, still unexposed any known product or technology can solve the problems referred to above brought due to the restriction of handset size size.
