Abstract :
The design and analysis of a novel ultrawideband hybrid electromagnetic band-gap (EBG)/ferrite structure that implements a combination of the mushroom type EBG structure with ferrite absorbing material were presented in [1, 2]. This design provides for a low-profile and conformal ultrawideband ground plane that is needed for backing ultrawideband antennas with minimal impact on the achievable bandwidth. As was reported in J. M. Bell, et al., 2004, the hybrid design offers a bandwidth exceeding 40:1 ranging from 120 MHz to 4.86 GHz.
