ANTENNA SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an antenna system that can effectively be downsized and weight-reduced and suppress variations in the antenna characteristics due to dispersion in the size and pattern of each antenna element.

SOLUTION: The antenna system is configured to include: a dielectric base 12 configured by layering and sintering a plurality of dielectric layers; a main antenna electrode 14 (main antenna element) formed in the middle inside of the dielectric base 12; a sub antenna electrode 16 (sub antenna element) formed to be inside of an upper part of the dielectric base 12; a via-hole 18 (connection part) interconnecting the main antenna electrode 14 and the sub antenna electrode 16; and two antenna electrodes 32, 34 placed to the via-hole 18 and whose tip is used for a free end.
