    • A tag antenna capable of reducing cost by removing through hole between antenna pattern and metal reflective sheet, and a tag including the same are provided to minimize a tag by forming an antenna pattern smaller than lambda/2 resonant length of an operation frequency. A tag antenna comprises a dielectric spacer(3) and an antenna pattern(1). The antenna pattern is formed in one surface of the dielectric spacer. A size of the antenna pattern is smaller than lambda/2 resonant length of an operation frequency. A slit pattern(4) is formed on the antenna pattern, and has length suitable for resistance component and capacitance component of a chip to be mounted. The antenna pattern has an antenna radiation resistance and an inductance. The inductance of the antenna pattern and the capacitance component of the chip satisfy a resonant condition. The antenna radiation resistance of the antenna pattern is identical to the resistance component of the chip.
