Design of Microstrip Patch Antenna for Practical Applications

Abstract

Different feeding techniques can be used for microstrip patch antennas and based on power transfer mechanism from feed to patch; they can be differentiated from each other. This report revolves around designing and simulating a microstrip patch antenna by using three feeding techniques namely coaxial feed, quarter wavelength feed and inset feed. The given antenna is excited using these feeds and the given design has been simulated and executed using HFSS. Different parameters of antenna like gain, radiation pattern and bandwidth have been presented in this report. Amongst the three feeding techniques, the coaxial feed gave the best results. Then using the coaxial feed, UWB antenna is designed as there is a need for a large frequency range. The challenges of this UWB antenna are then overcome by designing the UWB-MIMO antenna. The UWB-MIMO antenna helped us overcome the challenges but resulted in large mutual coupling. The designing of the T-shaped UWB-MIMO reduced this mutual coupling and gave best results amongst all
