| الملخص: | This work presents the design, simulation and fabrication of a Sierpinski carpet fractal antenna with circular ring shaped defected ground structure (DGS). The proposed antenna was designed and simulated at the centre frequency of 5.8 GHz and fabricated on Rogers RT/Duroid 5880 substrate with relative permittivity, Sr of 2.2, substrate thickness, h of 0.38 mm and copper thickness, t of 0.017 mm. Computer Simulation Technology (CST) software was used in designing and simulation. Measurements of the parameters of the antenna were carried out by using Vector Network Analyzer (VNA). The antenna was designed with a circular ring shaped DGS. The performance of the antenna was improved through the implementation of the circular ring shaped DGS. Performance of the antenna was discussed in term of return loss (S11), voltage standing wave ratio (VSWR) and radiation pattern. The performance of the antenna was evaluated for various iteration of the Sierpinski carpet fractal antenna with DGS and without DGS. The results from the simulation and measurement was compared and discussed. The measurement result for center frequency was 5.82 GHz and the return loss was 27.323 dB. Both the measured and simulated values concur well and satisfied the specification. The antenna has achieved unidirectional pattern and can be used for RFID application. |
