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.
