A novel RFID-HIS-PRS reader antenna for the millimeter wave band 30 GHz.

ABSTRACT The use of radio frequency identification (RFID) at millimeter waves has led new applications such as high data rate short range communication, location sensing through narrow-beam antennas, and so forth. In this article, we present the design of an antenna operating in Ka band for RFID applications based on metamaterials. The frequency band of around 30 GHz, allowing a spectral width of 5 GHz, is a possible solution for the integration of radio frequency devices specially a notched patch antenna at 30 GHz with coplanar feed was designed and characterized. The measurements made with the HP 8510p XF network analyzer are consistent with the simulations using the electromagnetic simulation software CST-MW Studio. On this antenna, we used primarily a high impedance surface (HIS) to prohibit the propagation of waves. A partially reflective surface layer is added to this HIS-antenna to increase its directivity and widen the bandwidth. The latter has −25 dB of insertion loss with an impedance bandwidth of 1 GHz and a gain of 14.3 dB at 30 GHz. © 2015 Wiley Periodicals, Inc.
