Design Construction of a Compact Microstrip Antenna with High Gain Working For RFID Band
Abstract
Radio Frequency
Identification (RFID) is the wireless non-contact use of radio frequency waves
to transfer data. Tagging items with RFID tags allows users to automatically
and uniquely identify and track inventory and assets. This work deals with the
design construction of a compact Microstrip antenna which has a high Gain along
with a sufficient Return Loss (S11) and Impedance bandwidth that will work for
India RFID band (860 MHz – 960 MHz) ISM band RFID Applications. The antenna has
been designed and simulated on a Fire Resistant FR4 Epoxy substrate. The
antenna has overall dimensions of 34 x 46 x 1.5 mm3 and has a Microstrip line
feed matched to 50Ω. The impedance bandwidth achieved by the final design is
about 49 MHz at the 857MHz - 1000MHz ISM band and has an S11 about -32 dB. The
final design has a very good radiation pattern. The antenna has been designed
using Ansoft High Frequency Simulation Software (HFSS). Software and hardware
results are similar.
