A compact half-Sierpinski fractal antenna is presented for UHF RFID applications. Taking the thickness of the substrate (177 µm) and compactness (length: width <2∶1) as constraints, the fractal antenna was studied for the highest exhibited gain. A gain close to 0 dBi (−0.64 dBi) with a return loss of less than −10 dB at 915 MHz was observed.
