WIDEBAND SPIRAL ANTENNA USING MAGNETO-DIELECTRIC MATERIAL

摘要

PURPOSE: A broadband spiral antenna using a magneto-dielectric material is provided to reduce an operating frequency of a high frequency band using a magneto-dielectric material with high dielectric permeability and magnetic permeability, thereby miniaturizing an antenna. CONSTITUTION: A ground surface(120) is made of a conductive plate. A power supply cable(130) is connected to the center of a radiation device through the center of the ground surface. A magnetic dielectric material(140) surrounds a power supply cable. An air layer separates the third magnetic dielectric material(143) from the fourth magnetic dielectric material(144).
