Title:
【発明の名称】フィルタ・アンテナ装置
Document Type and Number:
Japanese Patent JP2846482
Kind Code:
B2
Abstract:
A strip conductor plate connected to a feeder line is provided on a ground conductor via a dielectric substrate in order to feed electricity to an inverted-F antenna which has a nearly rectangular plate-like conductor forming a radiation conductor and the ground conductor arranged in parallel with the plate conductor. Therefore, the electricity is fed from the feeder line to the inverted-F antenna (37) through the electric field coupling between the plate-like conductor and the strip conductor plate. The inverted-F antenna and a resonator are coupled together via a coupling means for impedance matching, and a band-pass filter is constituted of the inverted-F antenna and the resonator (62).
