CIRCULARLY POLARIZED ANTENNA FOR UHF BAND RFID READER

摘要

PURPOSE: a kind of UHF RF ID readers of circular polarized antenna, which are provided to, to be provided the advantage that, i.e. reduction reflection loss, while minimizing size. ;CONSTITUTION: a kind of UHF RF ID readers of circular polarized antenna include substrate (110), dielectric substrate (120), and radiant panel. The substrate is made of aluminium alloy. Grounding parts (122) are formed in dielectric substrate and are connected to conductive material. ;The 2011 of copyright KIPO submissions
