ABSTRACT:
A broadband antenna apparatus includes a conducting ground plate, on which a three-dimensional member rests. A radiating conductor is stuck or printed on the three-dimensional member in such a manner that at least part of the radiating conductor is opposite to at least part of the ground plate. A wavelength shortening effect is achieved by the interposition of the three-dimensional member between the opposite parts of ground plate1and radiating conductor. This effect makes the broadband antenna apparatus smaller and lower in structure.
