ABSTRACT:
An improved space-filter formed as a composite multi-layered structure. Utilizing a periodic slot array structure nested between first and last strata of a dielectric material, the filter exhibits a constant bandwidth characteristic over a broad range of angles of incident radiation. Where two slot arrays are utilized in parallel relationship, an intermediate dielectric layer is provided which has an effective dielectric function selected to achieve critical array component coupling.
