摘要：
This paper presents the design of a circularly polarized (CP) antenna for Radio Frequency Identification (RFID) reader using the ring slot microstrip antenna for Ultra High Frequency (UHF) band. The proposed antenna, which consists of a ring slot microstrip antenna with truncated U-slot, is placed on a FR4 substrate (epsilon(r) = 4.5). The prototype antenna was fabricated with a total size of 100 X 100 X 1.6 mm(3) which shows a measured impedance matching band of 830-970 MHz as well as measured rotating linear based circularly polarized radiation patterns.
