<P>PROBLEM TO BE SOLVED: To provide an on-vehicle antenna capable of obtaining a good antenna characteristic at either a low-frequency band or a high-frequency band, and further saving a space. <P>SOLUTION: An on-vehicle antenna 100 comprises a substrate 140, a pedestal 130 arranged on the substrate, a power feeding element 110 arranged on the pedestal; and a non-power feeding element 120 coupled with the power feeding element. The power feeding element 110 has a power feeding element part 111 connected to the substrate 140 and extending in an approximate vertical direction; an antenna element 116 for an fH-band connected to the power feeding element part 111 and extending in an approximate right-angle direction from the power feeding element; and an antenna element 114 for an fL-band connected to the power feeding element part 111 and extending in a direction opposite to an extension direction of a main portion of the antenna element 116 for the fH-band. Then, the extension direction of the main portion of the antenna element 116 for the fH-band is different from the extension direction of the main portion of the antenna element 114 for the fL-band by 180° on an upper face of the pedestal 130. <P>COPYRIGHT: (C)2013,JPO&INPIT |
