<P>PROBLEM TO BE SOLVED: To provide an antenna, packaged in various mobile communication devices for use, which improves radiation characteristics and is low in price. <P>SOLUTION: The antenna includes an antenna element part by printing a lower conductor layer 2 and an upper conductor layer 16, which overlaps the lower conductor layer 2, on a base sheet 1 using conductive paste in accordance with screen printing. In that case, in a portion that becomes a high frequency band antenna element part, an outer frame 17 overlaps a rectangular part 3 and that portion includes positions at which thickness is partially different. In such a configuration, the usage of conductive paste can be reduced without damaging radiation characteristics and the antenna can configured at low cost. <P>COPYRIGHT: (C)2010,JPO&INPIT |
