Comparison and Analysis of Different Feeding Techniques for MIMO Antenna's UWB Applications with Defected Ground Structure

This paper demonstrates the working of UWB MIMO antenna with individual and common feedline ports for excitation. Etched on a highly reliable dielectric, the functioning of designed antenna at different working states of radiating patch elements is evaluated and presented. Furthermore, the detailed study and analysis of the generated responses of antenna with common feeding system is elucidated. The variations of the antenna characteristics, geometrical modifications and design parameters are discussed.
