Mutual Coupling Isolation of MIMO Antenna for ISM and C-Band Applications

Multiple Input Multiple Output (MIMO), Mutual coupling, Defected Ground Structures (DGS), Fixed Satellite Services (FSS), Radio Satellite Services (RSS), Radio Altimeters.

Ground irregularities also known as Defected ground structures (DGS) is a freshly presented innovatory way in designing of patch antennas to boost up the performance of antenna constraints. This study presents a novel proposal of ground irregularities or defected ground structure is proposed for suppression of mutual coupling effects among multiple input multiple output patch array designed on Roggers Duroid 5880. The two M shape structures surrounding Dumbbell Shaped structure and sandwiching Dumbbell shape patterns displayed the momentous level of surface wave dominance up to -42dB while maintaining the gain of 4.8dB and 5.57dBi of directivity. The patch array operates at 4 to 4.3GHz for Fixed and Radio satellite services (FSS) and (RSS) and radio altimeter application systems.
