Comparative study of EBG structure for application in Planar Antennas
Project Area of Specialization
Project Summary
Different EBG unit cells were designed and optimized using CST MW Studio. The structures were Mushroom, Swestika, and Cross Hair. The unit cells were populated into an array to place the cells in a linear patch antenna array of 2 elements. The performance of all the structures was compared and the best was fabricated for a practical design. The results were well in agreement with the measured results.
Project Objectives
1- Design of Unit Cells of Mushroom, Swestika, and Cross Hair EBGs at 4 GHz.
2- Performance improvement of linear antenna array using the designed EBG unit cells.
3- Comparative study of the designed EBG cells for optimal performance in antennas.
Project Implementation Method
1- Literature Review
2- Design of EBG Unit Cells on CST MW Studio
3- Population of Unit Cells into arrays.
4- Performace study of the EBGs in linear antenna arrays.
5- Fabrication of the optimal EBG design for antennas.
Benefits of the Project
1- Less Electromagnetic Coupling in linear antenna arrays.
2- Can be used for RADAR Applications.
3- Less Interference due to better isolation
4- Can be used for Base Station Units.
