Title:
フィルタ・コーティングを有する共振子を備えるアンテナ及びそのようなアンテナを含むシステム
Document Type and Number:
Japanese Patent JP5469054
Kind Code:
B2
Abstract:
The invention relates to an antenna for transmitting or receiving electromagnetic waves at a working frequency fT, that comprises a resonator with a filtering (49) coating that covers the major portion of the upper face of a reflector (22) located inside a cavity (36), the coating (40) being capable of removing all the electromagnetic waves having a frequency fT, and propagating in a direction parallel to the upper face of the reflector, without removing all the electromagnetic waves having a frequency fT and propagating in a direction perpendicular to the upper face of the reflector.
