摘要： 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.

摘要： A chip antenna that is simple in structure, produces small variation in antenna characteristics between individual antennas, and requires no circuit adjustments, is excellent in productivity. The chip antenna is capable of being mounted on a circuit board, as well as a wireless terminal using the chip antenna. A method of fabricating the chip antenna. A core body is made from an insulating material in a quadrangular or circular cylinder shape. A conductor in a helical shape is mounted on the side surface of the core body. A terminal portion is provided on the core body and electrically connected with an end portion of the conductor. The width, depth, and length of the core body are within ranges of 0.5-5 mm, 0.5-5 mm, and 4-40 mm, respectively. Intrinsic volume resistance and relative dielectric constant of the material are 1013 Ω·m or above and 40 or below, respectively.
