ABSTRACT:
An antenna (100) has a low reluctance material (140) positioned to influence radiation pattern. The antenna (100) includes a radiator (110), and the low magnetic reluctance material (140) is positioned in close proximity to a particular side of the radiator (110). The low reluctance material (140) has a primary function of providing a preferred path for the magnetic field generated by the radiator (110), thus confining the magnetic energy and reducing radiation along at least one side of the antenna (100).
