  1. Electromagnetic Band-Gaps (EBGs) have been extensively used in low-profile antenna designs because of their in-phase reflection characteristics in certain frequency band(s). EBGs have also been used as attractive ground planes and in checkerboard surface variations. The incident waves on checkerboard patches induce current densities whose amplitud...

  2. High Impedance Surfaces (HIS) are one of the breakthroughs that emerged in the modern antenna design area in 1999. HISs are ideal candidates as antenna ground planes because of their near perfect magnetic ground conductor (PMC) behavior at particular ranges. However, current rectangular designs have a limited performance and lack efficiency in the ...
