  • Patent number: 9853364
    Abstract: 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.
