【 摘 要 】

This paper deals the generation of chirped delay (CD) effect in microwave regime. For the purpose of achieving reflection dispersion, electromagnetic band-gap (EBG) structures with different rejection frequency are fabricated in different position by modulating the thickness of substrate. Microwave with different frequency will be reflected in different position, so non-flat reflected group delays responses can be obtained. One CD-EBG with 6–10 GHz operation frequency range is designed, fabricated and measured. Different group delay responses are obtained when feeding from different ports. Finally, temporal characteristic of the CD-EBG is studied by simulation and two chirped impulses are obtained.
