Direction angular visualization device equipped antenna device, and direction angular visualization device

摘要

PROBLEM TO BE SOLVED: To match the directivity of an antenna for carrying out transmission/reception in viewable section in a subscriber wireless system or the like making a FWA (fixed wireless access) with that of an opposed antenna and to avoid or reduce the effect of an obstacle present within the antenna directional angle.;SOLUTION: A directional angle visualizing unit 30 being a cylinder whose inner diameter and length have dimensions that enable a scenery within a prescribed directional angular range to be viewed at another end when looking from one end of the cylinder, is fitted to an antenna main body 10 in parallel with the directivity of the antenna main body 10. The directivity of the antenna is decided through the continual visual observation of the opposed antenna within the line of sight of the directional angle visualizing unit.;COPYRIGHT: (C)2004,JPO&NCIPI
