ANTENNA HAVING A FEEDING STRUCTURE, AND A FEEDING METHOD

摘要

Provided is an antenna having broadband frequency characteristics due to the use of a power supply structural body having a closed loop consisting of a conductive circuit and an inductive element, such that the capacitance due to a capacitive element and the inductance due to the closed loop give rise to resonance, and the magnetic flux generated in the closed loop at the resonance frequency is coupled to a radiator. Also provided is an antenna having broadband characteristics in a plurality of bands.
