<P>PROBLEM TO BE SOLVED: To provide a wideband and highly efficient antenna, and to provide a mobile wireless communication device provided therewith. <P>SOLUTION: A circuit board 101 has a base material 31 and an electrode which is formed on the external surface. A feeding element 201 is composed of a dielectric substrate 41 and an electrode which is formed on the external surface. On the top surface of the base material 31, a grand electrode 32 and a wire electrode 33 are formed. A first end of the wire electrode 33 conducts to the ground electrode 32 at a ground end SCE, and a second end of the wire electrode 33 extends to a second end surface of the base material 31, which is adjacent to the first end surface. On the second end surface of the base material 31, a wire electrode 34 is formed, and a first end of the wire electrode 34 is opened at an open end OE. A second end of the wire electrode 34 conducts to the second end of the wire electrode 33. A non-feeding element 35, one end of which is grounded at the ground end SCE, and the other end of which is opened at the open end OE, is structured by the wire electrodes 33 and 34. <P>COPYRIGHT: (C)2011,JPO&INPIT |
