ABSTRACT:
An antenna device, comprising a dielectric substrate board (10), dipole means (16) formed on the substrate board (10), and reflector member (48, 70, 72) having first and second reflective surfaces which are aparallel to each other define a first angle between each other. A positional relationship between the substrate board (10) and the reflector member (48, 70, 72) is such that the substrate board (10) and a vertex of the first angle (α) substantially lie in the same plane and the first and second reflective surfaces lie on opposite sides of the plane, a second angle defined between the substrate board (10) and the first reflective surface being different from zero each. In this way, an antenna device suitable for use in a broad 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 member (48, 70, 72) with respect to the substrate board (10).
