Abstract: Disclosed are an apparatus and a method for transmitting a tag. The apparatus for transmitting a tag converts 2 bits of a plurality of bit data into one symbol using phase information and orthogonal information. The apparatus for transmitting a tag generates a sub-carrier signal by multiplying the symbol by a square wave having a faster period by a predetermined number of times than a period of the symbol, and transmits the sub-carrier signal to a reader
