: The wireless communication industry is currently experiencing a tremendous growth in the area of Radio Frequency (RF) and antenna design. Researchers are trying to find new ways to design antennas with high data rates and low power consumption. Ultra-wide band (UWB) MIMO (Multiple Input Multiple Output) antenna design is an ultimate choice for short-range wireless applications. For UWB technology, the frequency spectrum, ranging from 3.1 to 10.6 GHz (7.5 GHz bandwidth), has been officially allotted by the Federal Communication Commission (FCC) in USA. Hence, the use of MIMO antenna concepts for UWB technology offers a potential solution for data rate enhancement with low power consumption. Despite having various benefits, MIMO technologies in communication systems are accompanied by some challenges that need proper attention. One of them is to achieve compactness of the overall design while maintaining a good performance. Achieving compactness increases the mutual coupling due to current flow among the ports, which results in poor diversity gain, low radiation efficiency, and low gain. Through proper isolation between the antenna elements, high mutual coupling is avoided. Different methods have been explored and proposed by researchers to enhance isolation among the antenna elements. This project explores the design of Multiple-Input Multiple-Output (MIMO) antennas tailored for Ultra-Wideband (UWB) applications, focusing on achieving high isolation between antenna elements. To achieve high gain and better VSWR, different substrate materials used in this project are: 1. ROGGERS 4003 2. FR4 EPOXY 3. ROGGERS R03006(tm) 4. AIR 5. ROGGERS R04350(tm).
