摘要：In this Research work, a Rectangular microstrip patch antenna loaded with rectangular patch antenna using Symmetrical Circuitous Structure Loaded with metamaterial structure is designed at a height 3.2 mm from the ground plane by using CST-MWS software. This material is said to have simultaneous negative parameters or double negative parameters (DNG Parameters) of the permittivity and permeability. It improves gain due to its negative refractive property the resonance frequency that we have used here is 2GHz. There are many parameters those are associated with antenna here in this paper we have considered return loss, directivity , VSWR and bandwidth of antenna The Return loss of the proposed antenna is reduced by 14.28dB. Voltage Standing Wave Ratio has also reduced from 1.63 to 1.09 bandwidth and directivity of proposed antenna have also showed significant improvement. upto a significant of this antenna has also increased upto 27MHZ that shows improvement in antenna property by proposed design. This antenna can has many applications in communication at L-band. For simulating our proposed antenna we have used CST-2010 simulator. CST is a tool that provides 3D view of the simulated antenna so directivity can be understands in a easy way. In this view it provides different colors for different region so when directivity is high it can be easily indicated by this tool polar plot of directivity can also get.
