Abstract

In this study, an attractive compact and high gain antenna design suitable for radio-frequency identification (RFID) and energy harvesting (EH) applications in the UHF band (ultra-high frequency) is proposed. The antenna is a potential candidate for wireless applications for sub-GHz and low UHF frequency band. It is constituted of two by one an inter-digital metal structure fed by co-planar wave-guide (CPW) configuration. The size of a single element is 25 × 35mm2. The antenna features a simple structure and small size of 35× 63mm2 or 0.08 _o× 0.21 _o. The antenna is fabricated on a low-cost FR4 0.8mm substrate. The experimental measurements were conducted to verify the practical results with the simulation performances. The operating bandwidth of the proposed antenna is around 340 MHz and extending from 920 MHz to 1.26 GHz with reflection coefficient of 6 dB. The peak realized gain is 4 dBi and is propagated in the end-fire direction. The design simulation was accomplished using the electromagnetic HFSS software. A good matching results were obtained between the simulated and measured results.
