Title:
ANTENNA SYSTEM
Document Type and Number:
Japanese Patent JP2000349532
Kind Code:
A
Abstract:
To miniaturize an antenna system while avoiding gain reduction and narrow frequency band.
An antenna section 20 and a filter section 18 are integrally formed on a dielectric board and the antenna section 20 and the filter section 18 are coupled via a capacitor to configure the antenna system 10A. In this case, a relation of 0.3×Lr≤Lt≤1.2×Lr holds, where Lt is an antenna length of the antenna section 20 and Lr is an antenna length measured by the antenna single body.
