Antenna with variable directivity pattern

A wireless apparatus, the antenna directive pattern which is provided controllably. Moreover considering the antenna viewpoint of key safe; the antenna to the directive pattern of forming antenna comprises at least one conductive element. Such conductive element (330 and 340) are connected at the feeding point (F) grounding point is connected with the ground signal. The conductive element with a part (331), wherein the length of probably corresponding to the operating frequency wavelength of the fourth, wherein the part of the grounding point (G) is coloured with radiation unit (320) with direction opposite direction. The component is used is directive antenna pattern is bottom of the frequency range access. Additionally, conductive element with the second part (332), the second part of grounding point directional radiation components feed direction; and in order to the need of directive pattern width of the frequency range of active.
