    摘要： Provided is a dual polarization antenna realized by using four inverted F-type radiators and a Radio Frequency Identification (RFID) reader employing the dual polarization antenna. The dual polarization antenna includes a ground plate and four inverted F-type radiators set up on the ground plate. Currents of the same phase are fed to the first and second inverted F-type radiators each other. Currents of an inverted phase are fed to the third and fourth inverted F-type radiators each other. The four inverted F-type radiators form an angle of 90° with one another. The first and second inverted F-type radiators radiate electric wave of vertical polarization and the third and fourth inverted F-type radiators radiate electric wave of horizontal polarization. Since the dual polarization antenna has excellent orthogonal and isolation characteristics, the antenna can extend a transmission distance between the reader and the tag and improve a communication quality.

    摘要： Provided are a Planar Inverted-F Antenna (PIFA), a Radio Frequency Identification (RFID) tag using the PIFA. The present invention miniaturizes the antenna by using a meander line extended from a radiating edge of a radiation antenna and adjusting a resonant frequency of the antenna, and it performs impedance matching by adjusting capacitive reactance of the antenna. Also, it can perform impedance matching by using a stub having a slot formed therein and adjusting inductive reactance and capacitive reactance of the antenna. The present invention miniaturizes the antenna by using a plurality of shorting plates for shorting the radiation patch from a grounding surface and adjusting the resonant frequency of the antenna. The present invention also provides an inexpensive PIFA antenna with an excellent radiation efficiency by forming the radiation patch in the form of metal sheet in the antenna and floating the radiation patch in the air.
