|Applicants:||HUAWEI TECHNOLOGIES CO., LTD.
|Title:||MULTI-ANTENNA SYSTEM AND MOBILE TERMINAL|
Provided are a multi-antenna system and a mobile terminal. The multi-antenna system comprises: a first planar inverted-F antenna (PIFA) (10) which comprises a metal floor (11), a medium board (12), a radiation patch (13), a probe-shaped feeding unit (15) and a metal shorting pin (16), wherein the radiation patch is located on the upper surface of the medium board, and is connected to the metal floor through the probe-shaped feeding unit and the metal shorting pin; a second PIFA (30) which is mutually vertical to the first PIFA and comprises a metal floor (31), a radiation patch (33), a feeding unit (36) and a metal shorting patch (34), wherein the radiation patch is connected to the metal floor through the feeding unit and the metal shorting patch; and an isolated branch knot (2) which is located at the edge of one side on the upper surface of the medium board of the first PIFA which is close to the second PIFA. Therefore, the isolation degree of the multi-antenna system satisfies the operating requirements of a mobile terminal.
