Abstract: A reader antenna includes dipole antennas, the dipole antennas including: a horizontal dipole antenna having the characteristic of horizontal polarization; and a dipole antenna perpendicular to the horizontal dipole antenna and including a vertical dipole antenna having the characteristic of vertical polarization, wherein the horizontal dipole antenna and the vertical dipole antenna may both have the characteristic of circular polarization. The reader antenna can be easily stored in an electronic shelf because it is realized in an ultrathin structure using a single-layered dielectric substrate.

Abstract: Disclosed herein are a tag transmission apparatus and a signal transmitting method thereof. The tag transmission apparatus converts a plurality of data bits into a symbol, which is one of a plurality of symbols, and multiplies the converted symbol by a square-wave having a predetermined frequency to thereby generate a subcarrier signal. Here, in the case in which the plurality of data bits are n (n is a natural number larger than 2) bits, the number of the plurality of symbols is 2n.
