A Wideband Circularly Polarized Stacked Patch Antenna With Truncated Corners Ground Plane for Universal UHF RFID Reader
This paper presents a wideband circularly polarized stacked patch antenna with truncated corners ground plane for universal UHF RFID reader. The configuration of the antenna composes of a slanted elliptical patch, corner truncated patch, a horizontally meandered strip (HMS), and corner truncated ground plane. One end of the HMS is connected to an SMA connector, while the other end is connected to the radiating patch via probe. In order to improve the bandwidth, the parasitic patch is used by placing above the radiating patch. From the simulated results, the proposed antenna has an impedance bandwidth of about 18.6% (800 – 965 MHz), a 3-dB axial ratio (AR) bandwidth of around 18.3% (816 – 981 MHz), and maximum gain of 8.4 dBi. The proposed antenna can operate in the frequency range of 840 – 960 MHz. Therefore, it is suitable for applying in universal UHF RFID reader.
