A circularly polarized antenna for UHF RFID reader
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 (εr = 4.5). The prototype antenna was fabricated with a total size of 100 × 100 × 1.6 mm3 which shows a measured impedance matching band of 830-970 MHz as well as measured rotating linear based circularly polarized radiation patterns.
