ABSTRACT:
An antenna attached to a window glass for transmitting and receiving ultrashort waves includes a primary antenna having a first feed point which is electrically connected therewith, a secondary antenna having a second feed point which is electrically connected therewith. A feeder is a coaxial cable having inner and outer conductors, an insulator disposed therebetween, and an outer cover covering the outer conductor. A first terminal which is electrically connected to the first feed point, a first holding portion for holding the inner conductor of the feeder so as to achieve an electrical connection between the first terminal and the inner conductor. A second terminal which is electrically connected to the second feed point has a second holding portion for holding the outer conductor of the feeder. The second holding portion has a through opening which is substantially rectangular or elliptical in shape for pouring thereinto a solder to achieve a soldering between the outer conductor and the holding portion. The through opening has a major side or a major axis, which has a length not shorter than 4 mm. Therefore, the solder can be poured into the through opening under the condition that the contact between the outer conductor and the holding portion is checked with the naked eye.
