  • Surface-mount type antennas and mobile communication terminals using the same
    Patent number: 6897815
    Abstract: A surface-mount type antenna and a communication terminal using the same. A radiator electrode is provided on a first principal face of a substrate. A ground electrode is provided on the second principal face of the substrate. A first feeder electrode has at least a portion thereof provided on a side face and on the second principal face of the substrate. A second feeder electrode is provided on an inner wall face of a hole formed parallel to the first and second principal faces. The first feeder electrode and the ground electrode are kept in a non-contact state. The first feeder electrode and the second feeder electrode are in electrical contact. A mobile communication terminal using the surface-mount type antenna is small in size, exhibits small variations in characteristics, and provides high productivity and reliability.
