    Miniaturised Microstrip Bandpass Filters Based on Moore Fractal Geometry
    (Taylor & Francis Ltd, 2015) Mezaal, Y. S.; Ali, J. K.; Eyyuboglu, H. T.
    This paper presents new microstrip bandpass filter design topologies that consist of dual edge-coupled resonators constructed in the form of Moore fractal geometries of second and third iteration levels. The space-filling property for proposed fractal filters has found to produce reduced size shapes in accordance with sequential iteration levels. These filters have been prepared for ISM band applications at a centre frequency of 2.4GHz using a substrate with a dielectric coefficient of 10.8, dielectric thickness of 1.27mm and metallisation thickness of 35 mu m. The output responses of each fractal bandpass filter have been determined by a full-wave-based electromagnetic simulator Sonnet software package. Simulated and experimental results are approximately compatible with each other. These responses clarify that these fractal filters have good transmission and return loss characteristics with blocked higher harmonics in out-of-band regions.
