| Summary: | The paper presents a rectangular stepped patch
antenna with defective ground plane using metamaterial based
split ring structure for RF energy harvesting applications at
downlink radio frequency range of GSM-1800. The aim of this
design was to enhance the antenna performance with regards to
impedance bandwidth and return loss. A simulation study of the
design was carried out in the Computer Simulation Technology
(CST) microwave studio. The results at the resonant frequency
1.845 GHz showed that the impedance bandwidth has increased
to 596 MHz, return loss have lowest value of -27.7 dB and VSWR
of 1.086. There is an improvement in performance with
metamaterial based antenna. |
