Abstract (en)

[origin: EP1195847A2] An antenna system and an artificial magnetic conductor (300) include a frequency selective surface having a frequency dependent permeability mu 1z in a direction normal to the frequency dependent surface, a conductive ground plane (806), and a rodded media (808) disposed between the frequency selective surface and the conductive ground plane. <IMAGE> <IMAGE>
