Microstrip Patch Antenna with Cross-Slot for UHF RFID Handheld Reader Applications
It is an automatic identification technology. This technology provides wireless identification and tracking. This paper presents a microstrip patch antenna with cross-slot for UHF RFID handheld reader applications. A square patch with unequal length cross slot and diagonally symmetrical two circular and two square slots are used to achieve compact size. The coaxial feed is used to excite the proposed antenna. The 10dB return loss bandwidth and VSWR of proposed antenna are 15.5MHz (914.3-929.8) and 1.6 respectively.
