Miniaturization of RFID reader front-end circuit based on low temperature co-fired ceramic

Miniaturization of radio frequency identification (RFID) reader front-end circuit based on low temperature co-fired ceramic (LTCC) is studied in this paper. LTCC makes the dimension of the circuit a reduction of about 30% which is compared with the traditional circuit substrate in ultra high frequency (UHF) band. It makes the size of RFID front-end circuit more compact than the traditional one.
