Abstract (en)
[origin: EP0929116A1] The invention provides an antenna device (10), comprising: an antenna unit (13) including; a basic body made of at least one of dielectric ceramic and magnetic ceramic, at least one conductor (11) disposed inside or on a surface of the basic body, and a feeding electrode (12) for applying a voltage to the conductor (11), disposed on the surface of the basic body; a mounting board (17) on which said antenna unit (13) is mounted; a ground part (16) in association with said mounting board (17) and adapted to resonate with said antenna unit (13); and a length in the polarization direction of a radio wave of said ground part (16) being about lambda /4 or more, where lambda is a wavelength of the radio wave. The above antenna device (10) achieves a small-size and high-gain. <IMAGE>
