Abstract
An antenna device of an easily carried portable radiophone, is provided, by disposing a slot antenna within an interior of the portable radiophone. The antenna device improves sensitivity of the device by arranging a slot antenna so as to transmit and receive vertical- and horizontal-polarized waves through the slot antenna device, which is constructed such that a conductive material is coated on a case of the portable radio telephone, an omni-directional first slot antenna for a vertical-polarized-wave is disposed horizontally over said case, and a second slot antenna for slant vertical-polarized or horizontal-polarized waves is disposed in a predetermined angle below said case, thereafter coupling in parallel a coaxial cable for feeding an electrical signal between each given position on the first and second slot antennas.
