Title:
コーナリフレクタアンテナにおけるダイポール給電構造
Document Type and Number:
Japanese Patent JP2004510375
Kind Code:
A
Abstract:
The invention provides an antenna device, comprising a dielectric substrate board (10), dipole means (16) formed on said substrate board (10), and reflector means (48) having first and second reflective surfaces (50, 52) which are aparallel to each other and define a first angle between each other. A positional relationship between said substrate board (10) and said reflector means (48) is such that said substrate board (10) and a vertex of said first angle ( alpha ) substantially lie in a same plane and said first and second reflective surfaces (50, 52) lie on opposite sides of said plane, a second angle defined between said substrate board (10) and said first reflective surface (50) and a third angle defined between said substrate board (10) and said second reflective surface (52) being different from zero each. In this way, an antenna device suitable for use in broad variety of applications is provided which allows easy modification of its antenna characteristics by adjusting the angle between the reflective surfaces (50, 52) and/or the angular position of the reflector member (48) with respect to the substrate board (10).
