Design & Fabrication of Metamaterial inspired High-gain Ultra-wide band Antenna
Project Area of Specialization Wearables and ImplantableProject SummaryCommercial UWB systems require small low cost antennas and large bandwidth. It is a well-known fact that printed microstrip antennas present really appealing physical features, such as simple structure, small size and low cost. A narrow bandwidth is, however, the main drawback of the microstrip patch antenna. Some designs of the antennas can meet impedance bandwidth requirements, but the gains or sizes are not very good. Often the requirements are extremely difficult or physically impossible to achieve.
The main challenge to design a UWB antenna comes from the coverage of large bandwidth because the matching and energy transmission require to be verified for the entire bandwidth. Also, it is quite challenging to meet the characteristics of wide impedance bandwidth, high gain, omnidirectional radiation pattern and compact size. However, the traditional trade-offs such as size vs. efficiency and size vs. bandwidth still influence the characteristics and performance of antennas
To overcome these problems, the metamaterial technology can be applied to planar antennas to improve its overall behavior, and eventually, achieve the best performance. In this way, the application of metamaterial technology, on patch antennas, can result in an increase of its low gain and bandwidth.
Project ObjectivesThe basic aim of our project is to design a UWB antenna and increase its gain and bandwidth by using metamaterial structure.
The objectives of our research include:
- UWB high-gain antenna designing and analysis for different applications such as high accuracy radar, sensing/monitoring systems, positioning and localization systems, Bio-imaging applications, through-wall imaging systems.
- Design and analysis of metamaterial structure and understanding its role in optimizing the performance of microstrip patch antenna.
- Performance comparison of UWB antenna and UWB antenna with metamaterials.
- Size reduction of metamaterial based UWB antenna.
- To enhance performance such as gain and bandwidth.
- Fabrication of the metamaterial inspired optimized antenna and comparing the simulated and measured results.
We will use Computer simulation technology (CST) microwave studio for the design of antenna and metamaterial structure. In CST, We will observe different parameters and compare them in order to optimize our design for the required results.
