PLATE-FORM ANTENNA AND ELECTRIC APPARATUS WITH THE ANTENNA

PROBLEM TO BE SOLVED: To provide a plate-form antenna and an electric apparatus which can be built in easily in a portable terminal and an electric appliance or a wall in a small space, with low cost and superior general versatility, and achieve high efficiency by itself without using grounding conductor parts in the portable terminal and the electric appliance as parts of the antenna. SOLUTION: Two mono pole antennas and a slot antenna are electrically formed using each current on a first radiant conductor 3 and a second radiant conductor 4, by forming a slot 2 by making cuts in a conductor board 1, by forming the first radiant conductor 3 and second radiant conductor 4 by defining a boundary with the slot 2 and by supplying electric power through two opposite conductor edges forming the slot 2.
