Abstract:

The design of a microstrip antenna array for 2.45 GHz radio frequency identification (RFID) reader applications is introduced with measured results. The array is of simple structure, low sidelobe level and circular polarization characteristics. Its measured sidelobe level is -23.2 dB, and the measured VSWR≤2 impedance bandwidth is 130 MHz (from 2.44 GHz to 2.58 GHz), making it suitable for RFID applications.

Key words: microstrip antenna array; low sidelobe level; circular polarization; radio frequency identification  (RFID) reader
