MULTI BAND ANTENNA DEVICE

摘要

PURPOSE: A multi band antenna apparatus is provided to improve convenience of operation by reflecting a transmission radio wave using a radiation element of plane arrangement. CONSTITUTION: A plane arrangement radiation element(102) faces a feeding element(101). The plane arrangement radiation element reflects a radio wave transmitted through the feeding element. The radiation element includes a dielectric substrate(121), radiation patches(123) and a conductor(125). The radiation patches are arranged on one side of the dielectric substrate. The conductor provides the reference earth for the radiation patches.
