Design of Fractal-Based Dual-Mode Microstrip Bandpass Filter for Wireless Communication Systems

In this paper, a dual-mode microstrip bandpass filter is designed employing Peano fractal geometry. The filter design uses the square patch with a perturbation element added at the corner of the patch for dual-mode configuration. The proposed bandpass filter structure has been designed based on the second iteration Peano fractal curve at 2.45 GHz using two substrates (RT/Duroid 6010 and FR-4) and their performance is simulated for return loss and insertion loss. The design process is continued up to second iteration of Peano fractal in order to achieve the center frequency at 2.4 GHz, which can be used for WLAN applications. The comparison is made on the simulation results of the proposed fractal filter between the two substrates.
