If the tangential components are in phase then the resulting fields combine to give maximum radiated field normal to the surface of the structure. It is seen from Figure 2, if we consider direction of the field opponents at edges then, they are opposite directions and thus out of phase, hence they cancel each other.

Top view and side view of Rectangular Microstrip Patch AntennaĪs shown in Figure slots are separated by distance L, when, the width of the structure has a maximum voltage and minimum current, then, it acts as an open ended circuit. Two slots representation of Microstrip Patch Antenna is as shown in Figure 2.įigure 2. The first layer is about 9.225mm above the ground plane and the optimized distance of second layer is 10 mm. Also Configuration of Antenna with Double split ring metamaterial superstrate has been shown in Fig. The first layer is about 9.225mm above the ground plane and the optimized distance of second layer is 11.60mm. Figure 1a shows configuration of microstrip antenna with S coupled metamaterial superstrate. The distance of second layer from first layer is between /3 to /2. The second layer, improve beam shaping and bandwidth. Adjustment of first superstrate layer is the most important stage in antenna design and it is about one third of operation wavelength (/3) above ground plane which cause to gain increase. Metamaterial superstrate places above the patch of antenna for concentrating of radiation energy normal to itself. The operation frequency of antenna is 15.23 GHz. The Square patch feed by 50 coaxial probe is positioned 1.25mm off-center. With permittivity 2.2 and with 40 mmÃ-46 mm dimensions and height 1.575mm is used in the simulation process. Superstrate Microstrip antenna with square patch (5.6mmÃ-5.6mm) on the Roger RT/duroid substrate Many of these softwares are commercially available at a very high cost or in the least, are proprietary.ĭesign of Microstrip Antenna with Metamaterial Currently, several products in which computer tools are used have been developed such as Ansoft Ensemble, IE3D, MWO (Microwave Office), SONNET, ADS (Agilent Advance Design System), COMSOL, MATLAB ,HFSS (Highįrequency Structure Simulation) etc for modeling and simulation of complicated microwave and RF printed circuit, antennas, and other electronics component.

This aspect is strongly related with wave propagation, where the propagation properties of the waves or how to plot the radiation patterns of antennas are not so easy to understand for undergraduate students, due to simple, static, oral explanations. Studying antennas and wave propagation phenomena using interactive graphics and animations becomes nowadays a fundamental tool for describing and understanding electromagnetic concepts. There-fore, the miniaturization of the antenna has become an important issue in reducing the volume of entire communication system. In modern wireless communication systems, the microstrip patch antennas are commonly used in the wireless devices. The performance of a rectangular patch antenna array on a metamaterial substrate was studied relative to a similar array constructed on a conventional FR4 substrate.
Moreover, we have also indicated the appropriate choice of particular metamaterial for different specific purposes like antenna size reduction and other mode modification-related applications. The performance of the fabricated antenna was measured and com-pared with simulation results. This indicates that the future communication terminal antennas must meet the requirements of multi-band or wideband operations to sufficiently cover the possible operating bands. The future development of the personal communication devices will aim to provide image, speech and data communications at any time, and anywhere around the world. In the recent years the development in communication systems requires the development of low cost, minimal weight, low profile antennas that are capable of maintaining high performance over a wide spectrum of frequencies. Understanding the behaviour of the Microstrip Patch Antenna and Design of it for different metamaterial with the use of the Graphical User Interface using MATLAB is better way of Analysis. Effect of changes in basic parameter microstrip Patch Antenna on its Radiation Patter and other parameters can be determined by using GUI. This is achieved by designing a friendly graphical user interface (GUI) for microstrip patch antennas through which antenna parameters and radiation pattern can be determined. This paper provides details on how to investigate a new method of teaching microstrip patch antenna design made by Metamaterials using MATLAB. & C.ġ,2Department of Electronics & Communication, Geentajali Institute of Technical Studies, Udaipur, Rajasthan, India Microstrip Patch Antenna Design Calculatorġ Mosin I Memon and 2 Prof.
