<p><P>PROBLEM TO BE SOLVED: To provide a surface-mounted antenna of a dual band by an antenna substrate. <P>SOLUTION: The surface-mounted antenna 90 has a substrate 10 consisting of a dielectric material or a magnetic material, first radiation electrode 21 formed on at least one surface of the substrate 10, second radiation electrode 22 arranged with a distance from the electrode 21 and having an open end 220 arranged on the surface different from a surface where an open end 210 of the electrode 21 is arranged, first grounding electrode 31 formed on the substrate 1 so as to be directly connected or capacitively-coupled to one end of the electrode 21, grounding electrode 32 formed on the substrate 10 so as to be directly connected or capacitively-coupled to one end of the electrode 22, and current-feeding electrode 40 opposite to both the electrodes 21, 22 with distances. <P>COPYRIGHT: (C)2004,JPO</p> |
