Abstract |
|
|
| The use of fractal geometries has significantly impacted many areas of science and engineering; one of which is microwave filters. Microstrip filters have been widely used in a variety of microwave circuits and systems, it has received much attention because of the advantages such as compact and simple structures, small sizes, easy fabrication and low cost, etc., and all these features are the requirement of the wireless communication systems.
The design of a hairpin-Koch filter has been proposed. This filter exhibits periodic frequency response. The spurious bands are being suppressed significantly through the implementation of Koch fractal on the micro strip coupled line. |
