The cable to waveguide transition apparatus having a signal accumulation form of a backshort, includes: a waveguide; a RF probe for transferring a radio frequency (RF) signal to the waveguide; and a backshort having the signal accumulation form for reflecting the RF signal excited from the RF probe, wherein the backshort reflects a first fundamental frequency signal excited from the RF probe to have a phase identical to a phase of a second fundamental frequency signal excited from the RF probe to an aperture of the waveguide, and reflects a first 2-order harmonic frequency signal excited from the RF probe to have a phase reverse to a phase of a second 2-order harmonic frequency signal excited to an aperture of the waveguide in order to eliminate the 2-order harmonic frequency signal.

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.

摘要： Provided is a planar inverted-F antenna (PIFA) which has a Co-Planar Waveguide (CPW) feeding structure and can be attached to a metal surface, and an RFID tag using the same. The PIFA includes a radiation patch layer; a Co-Planar Waveguide (CPW) feeding layer; a feeding probe; and a short-circuit. The CPW feeding layer includes a feeding means and a ground surface. The feeding probe electrically connects the radiation patch layer and the feeding means and provides a Radio Frequency (RF) signal to be radiated to the radiation patch layer. The short-circuiting means short-circuits the radiation patch layer and the ground surface through the dielectric layer. The PIFA can be applied to a passive RFID tag. Impedance matching between the antenna and the RFID chip is possible. Also, the PIFA can easily control resonant frequency of the antenna and reactance.
