PROBLEM TO BE SOLVED: To provide a dielectric antenna of a structure which can minimize the antenna even if the specific inductive capacity of the dielectric is not so enlarged so that the performance of the antenna may not be reduced. SOLUTION: A ground electrode 4 is formed in whole surface (rear surface) of a dielectric substrate 1 of plate type, such as ceramics, or a rectangular parallelepiped shape, and a radiation electrode 2 in which an end 2a is opened and the other end 2b is connected with the ground electrode 4 is formed on the surface 1a in which an interior or the ground electrode 4 of the dielectric substrate 1 is prepared and counters the one surface. It is prepared so that the end 3a may be made to counter and a power supply electrode 3 may perform a capacitive coupling to the open end 2a side of this radiation electrode 2, and the other end 3b is made as a power supply terminal. And, the end 5a of the loaded electrode 5 is made to counter open end 2a of the radiation electrode 2, and the other end 5b is connected with the ground electrode 4. COPYRIGHT: (C)2005,JPO&NCIPI
