In this paper, a MODEM for RFID system which operated in 900MHz UHF band is designed. Composition of modem is consisted of baseband part and RF part, and embodied to FPGA and micro strip antenna each. It is posible to adapt to RFID and zigbee system by use of the Modem which designed in this paper,
The implemented baseband part of RFID reader system is constructed as VHDL using ISE9.1i, design tool of Xilinx and I made an experiment on it tagetting Spartan2, FPGA device of Xilinx. Construction verification is measured each block through Logic Analyzer. In the RF part, produced microstrip patch style antenna and measured by Network Analyzer.
