A high impedance surface electromagnetic band gap (HIS-EBG) structure is proposed so as to design the core of a Hankel Inward Leaky Wave (HILW) antenna. HIS-EBG structure is expected to mimic a Perfect Magnetic Conductor (PMC), which is an alternative solution to the core absorber in order to generate properly the focusing spot with the HILW antenna. The proposed HIS-EBG structure is made of a mushroom-like structure that is dimensioned according to the 2-D dispersion diagram. The simulated electric field distribution with mushroom-like structure shows that the good focusing properties are close to the ones obtained in the PMC case, which agrees with the theoretical field distribution.
