Abstract
In this paper, we presented RFID multi-band reader antenna design that is worked in four UHF standard bands to cover all around the world RFID classification frequencies. This design works practically as a circular polarization so it will decrease the tag polarization disadvantage to the minimum effect. In this design, we found that this antenna design works in all the following frequencies (865 - 868 MHz (Europe), 902 - 928 MHZ (US and Australia), and 2.4 - 2.4835 GHz (across the world). This antenna is structured as a question mark shape radiating element with modifications. Such as a small half of a circular shape was added to the design to approve multi-band resonance. The antenna was partially grounded, so it doesn’t cover all the radiators underneath. Good results were achieved with an improvement and acceptable values of reflection and radiation performance for the targeted frequencies.
