Title:
デュアルバンド同軸アンテナフィードのためのマッチング及びパターン制御
Document Type and Number:
Japanese Patent JP6463092
Kind Code:
B2
Abstract:
A dual band concentric antenna feed is provided. The dual band concentric antenna feed includes an outer conductive tube and an inner conductive tube. The inner conductive tube is positioned inside the outer conductive tube and is coaxially aligned to a shared axis. A coaxial waveguide formed between the inner surface of the outer conductive tube and the outer surface of the inner conductive tube supports a first frequency band. A circular waveguide formed within of the inner conductive tube supports a second frequency band. The dual band concentric antenna feed also includes at least one transformer, a filter, and a plug in the coaxial waveguide. An impedance locus associated with the filter is high-frequency capacitive within the first frequency band and low-frequency inductive within the first frequency band. The plug is positioned near an aperture end of the concentric antenna feed.
