A new type of metamaterial-inspired monopole antenna designed for satellite transmission communication systems has been elucidated. By adding a 'C' Shaped Pair (CSP) metamaterial into the near field of monopole antenna resonating at 7.5 GHz, a secondary resonance has been created in C-Band which is lower than the monopole's ones. At this new resonance, the directivity of the structure was enhanced and its profile was reduced. Next, the tunability of the structure was observed with respect to the coupling distance between the monopole antenna and the CSP. The directivity of the structure has also been enhanced.

Left handed materials which have both negative permittivity and permeability, have been the area of potential research over a decade. This paper elucidates a Double Negative Group (DNG) Electric SRR, having 19.13THz as resonant frequency and having FR4 (ɛr=4.4) as substrate material. Nicolson Ross Wier (NRW) method has been used to retrieve the material parameters from transmission and reflection coefficient. Upon incorporation of splits in the structure, we find shift in resonance of permeability to a higher frequency at THz as the no. of splits increase. Also, the curve for resonance in permeability gets sharper i.e. less broadened with increase in splits (upto 3) on ESRR metamaterial. [ABSTRACT FROM AUTHOR]
