A Split Ring Resonator (SRR) as Metamaterial has been loaded on pyramidal horn antennas for Ku band or satellite application. The aim of this work is to exhibit the advantage of metamaterial (SRR) use inside horn antenna; this is mainly enhancement of the bandwidth towards lower frequency and improvement of the radiation pattern gain. The horn antenna is feed by a monopole antenna of optimised length. The obtained results from HFSS simulation concerning the constitutive parameters of the (SRR), show that there is a DNG (Double Negative) permeability and permittivity in the frequency of interest. In this work the operating bandwidth of the proposed antenna (notched band) is in the range of 9.80 GHz to 10.30 GHz, and 10.80 GHz to 11.20 GHz as Ku or satellite application.
