Two tri-band RFID tag and reader antennas are proposed in this paper. The primary aim of the proposed work isto achieve multi-band antennas by implementing fractal designs as radiating elements. The RFID reader antenna is createdby using modified fractal tree structure; the operating frequencies are 3.6 GHz, 5.8 GHz, and 8.2 GHz. The recursive rectangular is implemented in RFID tag antenna operates at 3.9 GHz, 5.9 GHz, and 8.2 GHz for the RFID applications of goods management, traffic toll fee collection, telemetry respectively. The proposed reader antenna achieved a highest read range of 87.5 cm and tag antenna accomplished 85.6cm.

In this work, the design of miniaturized dual‐ and triple‐ frequency Wilkinson power dividers using nonuniform coplanar waveguides is presented. The miniaturized configurations are achieved by replacing the conventional uniform arms with their equivalent multi‐frequency nonuniform transmission lines. The nonuniform width variation is governed by a truncated Fourier series expansion with coefficients optimized to obtain the desired multi‐frequency operation. The optimization process is carried out through the analysis of the even/odd mode circuits. The proposed dividers are simulated, fabricated, and measured to validate the design methodology. Simulated and measured results agree very well, and show input/output ports return loss and isolation better than 14.4 dB and transmission parameters in the range of −3 ± 2 dB at the design frequencies. Size reduction of 16.7% and 17.6% are achieved for the fabricated dual‐ and triple‐frequency dividers, respectively.
