PROBLEM TO BE SOLVED: To further broaden the frequency band of a compact antenna assembly. SOLUTION: Radiation electrodes 30 provided on an inner layer of a dielectric are shaped asymmetrically right and left to a symmetric axis passing the center, and the feed position of a feeder line to an antenna 15 of the antenna assembly 10 is off-centered from the antenna 15. These constitutions improve the frequency characteristic of the antenna assembly 10 to broaden the band. COPYRIGHT: (C)2008,JPO&INPIT
