ABSTRACT:
An antenna, a RFID tag using the same, and an antenna impedance matching method thereof are provided. The antenna includes: a radiation patch for deciding a resonant frequency of the antenna; a ground plate disposed in parallel to the radiation patch; and a feeder disposed between the radiation patch and the ground plate in parallel for providing a RF signal to an element connected to the antenna, wherein the feeder includes a microstrip feed line proximately coupled to the radiation patch by being formed perpendicularly to the resonant length direction of the radiation patch.
