High Impedance Surface Application to Dipole Antenna Design
Keywords:
Digital capacitance, EBG structures, metamaterials, negative index materials, wire antennaAbstract
In this paper, HIS (High Impedance Surface) are used, in order to verify their utilities; we have considered two different structures as a ground. The first is mushroom EBG (Electromagnetic Band Gap) structure which is composed of several patches with a ground connecting via, where the second is 2D metamaterial structure with resonant rings. Both the structures are investigated by simulation and compared at the frequency 12 GHz. The metamaterials proprieties are successfully verified around the resonant frequency.
