    摘要: Provided is an antenna for a Radio Frequency Identification (RFID) reader using an electrical loop. It includes an upper metal plate which functions as a radiator; a lower metal plate which is disposed apart from the upper metal plate by a predetermined distance and functions as a radiator; a ground plate disposed apart from the lower metal plate by a predetermined distance; and a feeding probe disposed at the center of the upper and lower metal plates. The antenna can perform radiation parallel to the earth's surface including other directions. Therefore, it is suitable for an RFID reader which recognizes an RFID tag attached in parallel to the earth's surface. The electrical loop antenna can control impedance matching, resonance frequency, antenna gain, and radiation pattern according to the distance between metal plates, size of the metal plates, thickness of a feeding probe, and how the metal plates are arranged.

    摘要: Provided is a multi-band internal antenna of a symmetry structure having stub, in which a size of the internal antenna can be reduced by stacking loop antennas, a broadband characteristic can be obtained in a high frequency band by connecting the stub to a top patch of the antenna, and a reduced SAR and an omni-directional radiation pattern can be obtained by configuring an antenna patch in a symmetry structure. The multi-band internal antenna includes: a top patch disposed in an upper portion of the antenna, the top patch being formed in a loop shape of which one end is opened; a stub connected to the top patch to expand a bandwidth of a high frequency band in an operating frequency of the antenna; a bottom patch connected to a ground part through a feeder part and a shorting part, the bottom patch being formed in a loop shape of which one end and another end are opened; a connecting part connecting the top patch to the bottom patch to transmit a signal from the bottom patch to the top patch; an intermediate part formed between the top patch and the bottom patch to a predetermined thickness; the feeder part for feeding power to the bottom patch; and the shorting part for grounding the bottom patch. The multi-band internal antenna is used in wireless communication fields.
