A multiple-antenna system includes a planar inverted-F antenna PIFA of a first type, which includes a metallic ground plane, a dielectric plate, a radiation patch, a probe-type feeding unit, and a metallic shorting pin. The system also includes a PIFA of a second type perpendicular to the PIFA of the first type and including a metallic ground plane, a radiation patch, a feeding unit, and a metallic shorted patch. The radiation patch is connected to the metallic ground plane by using the feeding unit and the metallic shorted patch. Isolation stub is located on an edge of a side, close to the PIFA of the second type, of the upper surface of the dielectric plate of the PIFA of the first type.

The present invention relates to the field of wireless communications technologies, and in particular, to a multiple-antenna system and a mobile terminal.
With rapid development of mobile communications technologies, application of small-sized mobile terminals, for example, mobile phones, is becoming increasingly popular. An air interface used by a small-sized mobile terminal to communicate with a base station and to receive and transmit a radio frequency signal is an antenna, and power of the small-sized mobile terminal is transmitted to the base station in a form of an electromagnetic wave by using the antenna. Therefore, the antenna plays a key role in the mobile communications technologies.
A planar inverted-F antenna (PIFA) is a common antenna used on a mobile phone and is increasingly widely applied to a mobile terminal because of advantages of the PIFA, such as a small size, a light weight, a low profile, a simple structure, and ease of integration.
