Antenna System and Antenna Module With a Parasitic Element For Radiation Pattern Improvements

Abstract

An antenna system and antenna module incorporating the antenna system. The antenna system has a first planar antenna element and at least one second antenna element which are arranged along an axis. Also included within the near-field of the first planar antenna element is a planar parasitic element 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. The deformation of the radiating pattern of the first planar antenna element, due to interference with the at least one second antenna element, is reduced.
