Title:
SURFACE-MOUNTING TYPE ANTENNA AND ANTENNA DEVICE MOUNTING THE SAME
Document Type and Number:
Japanese Patent JP2003110344
Kind Code:
A
Abstract:
To provide a surface mounting type antenna, to which directivity and bandwidth which are optimum to an antenna for Blue tooth are imparted, and an antenna device mounting the surface-mounting type antenna.
In the surface-mounting type antenna, a main radiation electrode and an auxiliary radiation electrode are arranged facing each other on dielectric or magnetic base material and are connected by using a connecting conductor. Since a style is used, where power feeding is performed to a junction part between the connecting conductor and the radiation electrodes by using a strip line, an impedance matching circuit is unnecessary, and very compact mounting is enabled.
