Abstract
In this paper, we present a design of a low-profile PIFA array antenna for a RFID tag mounted on metallic objects. With shorting pins placed at the inner edges of the patches, two quarter-wavelength microstrip lines with two additional matching stubs are needed in order to achieve conjugate impedance matching, and a broadband operation can be obtained. The effect of the spacing between the PIFAs on RFID tag reading range in the presence of metal plates is investigated.
