ANTENNA SYSTEM AND ANTENNA MODULE WITH A PARASITIC ELEMENT FOR RADIATION PATTERN IMPROVEMENTS

摘要

The invention relates to an improved antenna system and antenna module incorporating same. The antenna system comprises a first planar antenna element, and at least one second antenna element, which are arranged along an axis, and further a planar parasitic element arranged within the near-field of the first planar antenna element, the planar parasitic element being arranged substantially in parallel to the first planar antenna element and being arranged at a predetermined distance therefrom. The center of the planar parasitic element is offset with respect to the center of the first planar antenna element in a direction away from the at least one second antenna element along the axis, so as to reduce a deformation of the radiating pattern of the first planar antenna element due to an interference with the at least one second antenna element.
