Missiles ……. Feedings Microstrip patch antenna feeds with different mechanism feedings, the four most popular are : Coaxial Cable Microstrip Line Aperture coupled slot Feed Proximity coupled Feed To design a Rectangular patch antenna. The height of the dielectric substrate h. The height of the conductor t. The other parameters: The width of the patch -W The length of the patch -L The width and length of the Ground plane and the substrate -Wg -Lg There are a a lot of methods for analysis microstrip patch antenna: The Transmission Line model.
The Cavity model. Also, if the coax used for future antenna testing is a RG58 cable, should I change the inner, outer radius as well as the dielectric constant property of simulated structure based on the manufacturer's specs? In reality, the ground plane of the substrate will be fairly thin. It is made thick in the simulation due to ' port region must be homogeneous for at least 3 mesh lines in longitudinal direction' requirement. May I know which is the correct simulation method? Click to expand Do you mean that I need to add the structure of the coax connector for the simulation?
Therefore, may I know 1 or 3 is a better approach? Correction to my previous post. Resonant frequency for 1 and 2 are quite close, but why their S11 value are so different? I 've checked the line impedance of both ports and they are the same at Therefore, may I know what is actually affecting the S11 parameter in this case? Similar threads T.

This is power transmission graph plot from port 1 to port 2 S1,2. Smith chart plot represents antenna impedance variation with frequency. Figure 7 and 8 shows the smith chart of S parameter S1,1 and S2,2.
Smith chart can be used to convert reflection coefficient to normalized impedance. The smith chart is very helpful for power transmission analysis. Among the antenna applications of microwave and radio frequency substrate materials, the metamaterial is most relevant. The metamaterial antenna is used to design low profile and compact antenna system.
Metamaterial can also be used as part of feeding part of antenna system. Metamaterial gives utilization to upgrade the radiation and coordinating properties. At present time the popular appication of microstrip antenna design is suitable for. Square microstrip patch antenna with metamaterial provides wide band and high gain which is almost achieve in this project work. This technology may lay the foundation for anywhere wireless transferring in future.
Followings are future scope for improvement and further research. This project work can be further taken in research in order to enable tracking systemand other advanced application.
We wish to acknowledge the encouragement, guidance and invaluable support of our worthy Principal, Govt. Women Engineering College Ajmer for giving us an opportunity to explore our views and notions through this research paper. We also wish to thanks our colleagues for giving constant support and motivation which helped us to achieve the target.
The design of square microstrip patch antenna using metamaterial structure has completed in CST microwave studio software. We achieved good simulation result to satisfy our requirements. Most of the antennas has main drawback of impedance bandwidth. Our design and analysis of square antenna with metamaterial has focused on impedance bandwidth.
Thus simulation results provide wide bandwidth with low return loss and increase total efficiency. Tseng, S.
