A new high isolation dual-antennas with miniature decoupling network design

This study proposes a compact high isolation dual-antennas structure designed for Taiwan UHF RFID. The decoupling and matching networks just with reactive element, are used in order to avoid power loss. The function of the decoupling and the matching networks like a circulator provide high isolation in the transceiver, and an antenna 1 and an antenna 2 have the same radiation pattern at 915 MHz.
