ANTENNA DEVICE, ELECTRONIC DEVICE PROVIDED WITH THE SAME AND ELECTRONIC EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide an antenna device which is small-sized and obtains sufficient radiation with little unneeded radiation by providing a 1st connecting means that electrically connects an antenna pattern to a ground terminal on a planar pattern conductor and a 2nd connecting means that electrically connects power feeding terminals on the opposite surfaces. SOLUTION: A connection terminal 3 for ground is provided in a curved part A and the terminal 3 for ground is connected to a ground terminal 5 through a pattern conductor F formed on a side surface of a substrate 4 by a 1st connecting means. Also, a connection terminal 2 for power feeding is connected to a power feeding terminal 6 through a pattern conductor E formed on a side surface of the substrate 4 by a 2nd connecting means. Since a planar pattern conductor 7 is extended just close to the terminal 6, unneeded radiation can be minimized and sufficient radiation with little unneeded radiation can be obtained by providing the ground of an antenna power feeding line feeding power to an antenna device 9 on a planar conductor pattern extended just close to the terminal 6.
