RFID Reader block diagram from Texas Instruments ...

The RFID (Radio Frequency Identification-13.56MHz RFID system) essentially consists of an RFID Reader/Writer (Transceiver), an HF Tag and a Processor unit interfacing to various peripherals.

HF Tags

A wide range of HF Tags are available. Physical form factor and processing requirements of the HF Tag are the primary factors that help decide which tag to use. In addition, the amount, type and security level of the information which needs to be stored on the card determine the appropriate tag. TI provides HF Tags, suitable for paper and plastic lamination. Memory sizes up to 2kBit with different security levels are available.

UHF EPC Gen2 RFID-Reader Design

Portable Reader Design with Carrier Suppression

In UHF (Ultra High Frequency) RFID (Radio Frequency Identification) systems Rx (Receiver) is usually isolated from Tx (Transmitter) by a circulator or a directional coupler. Since tags become more sensitive in order to improve reading distance, the relatively poor isolation of 20dB - 30dB limits the tag to reader link. A way to improve a directional coupler's isolation is to mismatch the unused port to generate a...
