Multi-band switchable antenna for e.g. mobile telephone, has zones subjected to polarization potentials of respective polarization switching units to control switching states of units, where each switching unit traverses space forming slot

摘要

The antenna has a polarization switching unit (SW 1) whose terminals are connected to zones (Z 1, Z 2). Polarization switching units (SW 2, SW n-1) have terminals connected to the zone (Z 1) and one of other additional zones (Z 3, Z n). The zones (Z 2, Z 3, Z n) are subjected to polarization potentials of respective units (SW 1, SW 2, SW n-1) to control switching states of the units. Each switching unit traverses a space forming slot. An independent claim is also included for a mobile communication terminal comprising an antenna.
