| 摘要 |
<p>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 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 g(a) substantially lie in a same plane and said first and second reflective surfaces lie on opposite sides of said plane, a second angle defined between said substrate board (10) and said first reflective surface and a thirs angle defined between said substrate board (10) and said second reflective surface being different from zero each. In this way, an antenna device suitable for use in broard variety of applications is provided which allows easy modification of its antenna characteristics by adjusting the angle between the reflective surfaces and/or the angular position of the reflector (48) with respect to the substrate board (10).</p> |
