  • Abstract
    A trade off has to be made between bandwidth and isolation of array elements when designing phased arrays. When the isolation is achieved via a PCS-EBG that is aimed at reducing the TM00 mode only, the reduction of bandwidth could be even more important rather than the one obtained when using a more standard cavity backing. This is due to the need of using a higher dielectric constant.
