Title:
周波数に依存しない放射特性を有した広帯域マルチダイポールアンテナ
Document Type and Number:
Japanese Patent JP4675894
Kind Code:
B2
Abstract:
The invention describes a broadband multi-dipole antenna that has low input reflection coefficient, low cross polarization, rotationally symmetric beam and constant beam width and phase center location over several octaves bandwidth. The dipoles are fed from one or a few feed points, and they may with advantage have log-periodic dimensions. The antenna is more compact, has lighter weight and is cheaper to manufacture than other solutions. It is very well suited for feeding single, dual or multi-reflector antennas.
