This paper propose a new generation of antenna design that applies Meta material properties at the height of 3.2 mm above from the ground Plane. Paper also analyzed the performance of Ractangular Micro strip Patch Antenna with and without using the Meta material structure. All antenna parameters such as Return Loss, Gain, Directivity and Band width were measured. The main focus of this paper was to improve Return loss so that Patch antenna used for wide band applications. The additional features were its compact size and used in multiband operation.

A Rectangular micro strip patch antenna loaded with “Enhancement in RMPA parameters by Rhombus Cut Shaped Meta material high frequency using at 6.65GHz” As a rectangular microstrip patch antenna is designed at a height of 1.6mm & Left handed Meta material structure is designed at a height of 3.2mm from the ground plane by using CST-MWS software. The resonance frequency 6.65GHz of the designed antenna is using as a high frequency. We knew that frequency is increases as a bandwidth is also increases. Therefore in this paper work used at high frequency. The 10 dB impedance bandwidth of proposed antenna is 438.4MHz. The Return loss of the proposed antenna reduced to -34dB. This antenna is small size, cheap, compact and easy to fabricate, and achieve good radiation characteristics with higher return loss.

The antenna along with the proposed Meta material structure designed to Resonate at 8.0 GHz frequency. But the proposed Meta material cover significantly reduces the return loss and increases the bandwidth, and gain of the antenna in comparison to rectangular micro strip patch antenna. The Metamaterial substrate has a potential to reduce the circuit size of the antenna as well as maintain the amplitude of the return loss at the specific resonant frequency. The most attractive feature of the substrate is the ability of enhancing the bandwidth of a patch antenna at 8.0GHz frequency. The system is firstly modelled by Computer Simulation Technology Software (CST-2010). With the help of CST-2010, The return loss, directivity, & radiation pattern of compact rectangular Patch Antenna operating at 8.0 GHz frequency and rectangular Patch Antenna along with designed Meta material shape have been evaluated in this work.

A Rectangular Micro strip Patch Antenna (RMPA) along with meta material which has design of “Rectangle Cut Shaped’’ structure is proposed at height of 3.2 mm from the ground plane. The RMPA with proposed Meta material structure is designed to resonate at 2.097 GHz frequency. In this paper work focused on return loss & gain. The return loss & gain of the parameters of RMPA enhancing the performance of antenna for useful applications such as wireless application & long distance communication. Basically if return loss reduces then the signal is useful for long distance communication. Proposed Meta material structure is significantly reduced the return loss and increased the bandwidth and gain of the antenna with compare to RMPA alone. The gain is increased up to 3.242 in comparison to RMPA alone. The return Loss of proposed antenna is reduced to -41.9db.

In this paper, Rectangular Microstrip patch antenna has been designed for different substrate heights and dielectric constants of substrate. The proposed antenna is designed at a height 3.2 mm from the ground plane. This paper proposes a new generation of antenna that applies Meta material properties at ground Plane. The paper analyzes the performance of Microstrip Patch Antenna with and without using the Meta material structure. Effect of bandwidth due to change of substrate height and dielectric constant have been investigated. Finally, bandwidth for each substrate height and dielectric constant is measured for selecting the optimal patch antenna.
