<P>PROBLEM TO BE SOLVED: To provide a substrate mounting type antenna for improving the receiving sensitivity in a packaged substrate product being built in an electronic apparatus, and to provide a radio wave clock module and its using method. <P>SOLUTION: A connection counterbore 14 has a connection terminal 15 and connection terminals 151 and 152 are connected, respectively, with the connection lines 102a and 102b of the coil 102 of a bar antenna 100. The connection counterbore 14 is mounting the circuit portion 16 of a tuning capacitor being connected with the coil 102. A protection case 18 contains a part of the connection counterbore 14 including the bar antenna 100 and the circuit portion 16. A slit 181 is opened in the case 18 so that the connection counterbore 14 is inserted. The case 18 is arranged such that the bar antenna 100 can be rotated or slid by the slit 181 about the connection counterbore 14 as a fixed point. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
