Title:
超広帯域アンテナ及び超広帯域高周波回路モジュール
Document Type and Number:
Japanese Patent JP4176613
Kind Code:
B2
Abstract:
One of the objects of this invention is to realize an antenna having low reflection loss over an extremely wideband. The antenna of the present invention is provided with a dielectric substrate, a plurality of antenna conductors formed on one surface of the dielectric substrate that are pseudo self-complementary on the surface, and a plurality of feed conductors symmetrical with respect to symmetrical surfaces of the antenna conductors, wherein a gap for a wavelength of 1/10 or less that of the wavelength of a usage frequency in a vacuum is provided at a center of rotational symmetry between the plurality of antenna conductors.
