ANTENNA ISOLATION USING A TUNED GROUNDPLANE NOTCH

摘要

There is disclosed an antenna device relating to a single or dual band antenna system for use in mobile telecommunications devices, laptop and tablet computers, USB adapters and electrically small radio platforms comprising a pair of antennas attached to a conductive ground plane, the antennas being separated by free space in which at least one notch is formed in the conductive ground plane between the pair of antennas characterized in that the notch further includes an inductive component and a capacitive component providing good antenna isolation so as to enable MIMO operation or diversity operation.;Microsoft Corporation

1. A system comprising:
a conductive groundplane having a notch formed in an edge portion; two antennas connected to the conductive groundplane and positioned on opposite sides of the notch; a first electrical pathway connecting a first side edge of the notch to an opposite side edge and providing isolation between the two antennas at a first frequency of antenna operation; and a second electrical pathway connecting the first side edge of the notch to the opposite side edge and providing isolation between the two antennas at a second different frequency of antenna operation.
