Fractal microwave filters

2010 IEEE 11th Annual Wireless and Microwave Technology Conference (WAMICON), 2010
In order to meet the ever increasing demand for miniaturization of RF and microwave filters, the suitability of fractal resonators has been examined and a complete design method of miniaturized fractal filters has been developed.

Shrinking microwave filters

IEEE Microwave Magazine, 2008
An adaptive predistortion technique has been presented and verified through the design and fabrication of practical filters in both the C and Ku bands. The method allows the realization of microwave filters at a lower cost, lighter mass, smaller volume, and better performance with minimum insertion loss penalties.The concept of lossy filters has been ...

Photonic Microwave Filters

2006 International Conference on Microwaves, Radar & Wireless Communications, 2006
Novel photonic microwave filters based on time delay introduced by a dispersive media are presented. This is followed by description and analysis of issues concerning microwave filters theory, architecture, tuning, reconfiguration and processes of obtaining negative taps.

Microwave photonic filters

2010 Photonics Global Conference, 2010
Photonic signal processing offers the prospect of realising extremely high multi-GHz sampling frequencies, overcoming inherent electronic limitations. This stems from the intrinsic excellent delay properties of optical delay lines. These processors provide new capabilities for realising high time-bandwidth operation and high-resolution performance.
