Title:
ANTENNA DEVICE AND WIRELESS TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/122902
Kind Code:
A1
Abstract:
Parasitic elements in parasitic element arrays have strip shapes that are substantially parallel to the lengthwise direction of a dipole antenna, and the passive elements are formed at prescribed spacing. The parasitic element arrays are arranged so as to form a plurality of gaps through which radio waves from the dipole antenna are propagated, the arrangement being such that there is no overlap between a center axis produced by extending the dipole antenna lengthwise center point in the direction of conduction of a high frequency wave signals, and a center axis produced by extending the dipole antenna lengthwise center point of a parasitic element group constituted by the plurality of parasitic element arrays in the direction of conduction of the high frequency signal.
