Abstract
An internal antenna providing impedance matching for a wide band is disclosed. The disclosed antenna may include: a substrate; an impedance matching/feeding unit comprising a feeding member, separated from the substrate at a designated distance, configured to receive RF signals, and of a designated length in a first direction, and a ground member, separated from the substrate at a designated distance, separated from the feeding member at a designated in a second direction perpendicular to the first direction, and of a designated length in the first direction; and a radiator extending from the ground member; wherein the impedance matching/feeding unit performs impedance matching by way of coupling between the feeding member and the ground member, and the radiator receives coupling feeding from the feeding member. The disclosed antenna has the advantages of overcoming the narrow band problem of a planar inverted-F antenna, and of allowing more efficient utilization of space in an internal antenna.
