Abstract :
A new concept to design thin directional broadband antennas on EBG or HIS surfaces is proposed. Using our proposed concept an octave or more bandwidth is obtained with fairly thin EBG structures even at UHF frequencies allowing low profile antenna design and development. At the heart of the proposed scheme lies the concept of a non-uniform aperiodic EBG surface where the EBG patch size and their inter-element distance are varied according to a specific tapering profile.
