Antenna system and electronic equipment employing same

Abstract

The invention provides an antenna system, which comprises a metal back shell, a system ground unit, an upper antenna module and a lower antenna module, wherein the upper antenna module comprises a main low-frequency antenna, a three-in-one small antenna, a dynamic adjustable switch and a first ground point; each of the main low-frequency antenna and the three-in-one small antenna comprises a low-frequency feed point and a three-in-one small antenna feed point; the lower antenna module comprises a first medium-high frequency antenna, a second medium-high frequency antenna and a second ground point; and each of the first medium-high frequency antenna and the second medium-high frequency antenna comprises a first medium-high frequency feed point and a second medium-high frequency feed point. The invention further provides electronic equipment. The electronic equipment comprises the antenna system. Compared with a related technology, the antenna system provided by the invention has the advantage that the technical problem that the antenna performance is affected by holding in a hand is solved.

[0002] At present, mobile phones made of metal materials have become the mainstream models of mobile phones of various brands. The antenna design with metal materials was born. The three-stage metal shell mobile phone design is an ideal model that many manufacturers yearn for. However, with the three-stage metal shell The antenna of the mobile phone is greatly affected by hand-holding, which will greatly reduce the performance of the antenna and affect the normal use of the mobile phone

[0003] In the prior art, the three-section metal shell mobile phone often adopts the method of setting up and down dual antennas to solve the impact of hand-holding on the performance of the antenna. However, the performance of the lower antenna in this method is still greatly affected by the hand-holding, and the setting environment of the upper antenna is complicated. , the stacking of major mobile phone devices will seriously affect the performance of the upper antenna. It is difficult to design the upper antenna to cover the entire frequency band, and it is easy to cause SAR (Special Absorption Rate) to exceed the standard.
