The Tiered Umbrella-Shaped Monopole Antenna for RFID System Applications with 867 MHz

摘要

This paper presents the Tiered Umbrella - Shaped Monopole Antenna Applications for Industrial Scientific and Medical (ISM) with etching technique for RFID Applications. Antenna analysis and design are simulated by CST (Computer Simulation Technology) program for calculate suitable parameters and compare with real antenna. The prototype antenna structure was designed on print circuit board with FR4 with dielectric constant of 4.3 and thickness (h) of 1.6 mm. From measurement result, it was found that the impedance bandwidth of an antenna to be 42.04% (620-950 MHz) which cover requires a frequency is 867 MHz, the radiations pattern of omnidirectional style and gain 3.21 dBi for support RFID frequency.
