Bandwidth Enhancement of ? Shaped Stub Structure in Uwb Mimo Antenna for Wireless Applications
A compact ? Shaped Stub Structure of Multiple Input Multiple Output (MIMO) with enhanced band of operation is Ultra Wide Band (UWB) system is projected. The projected system involves double port excitations in addition of common earth or zero (Ground) elements with dimensions of 50×30mm2. ? designed stubs are presented on mutual earth element of the projected ? designed structure. The projected antenna like “pi” designed stubs Ultra Wide band multiple input Multiple output has enhanced Bandwidth, Mutual coupling reduction over the complete UWB range of frequencies. This proposed antenna covers Ku band of operation. The proposed ? Shaped Stub element is simulated the results like VSWR, S-Parameter, Radiation Pattern, Surface current distribution.
