In this paper,the investigation of a novel compact 2×2,2×1,and 1×1 Ultra-Wide Band(UWB)based Multiple-Input Multiple-Output(MIMO)antenna with Defected Ground Structure(DGS)is *** proposed Electromagnetic Radiation Structures(ERS)is composed of multiple radiating *** MIMO antennas are designed and analyzed with and without *** feeding is introduced by a microstrip-fed line to significantly moderate the radiating structure’s overall size,which is 60×40×1 *** high directivity and divergence characteristics are attained by introducing the microstripfed lines perpendicular to each *** the projected MIMO antenna structures are compared with others by using parameters like Return Loss(RL),Voltage Standing Wave Ratio(VSWR),Radiation Pattern(RP),radiation efficiency,and *** same MIMO set-up is redesigned with DGS,and the resultant parameters are ***,the Multiple Input and Multiple Output Radiating Structures with and without DGS are compared for result considerations like RL,VSWR,RP,radiation efficiency,and *** projected antenna displays an omnidirectional RP with moderate gain,which is highly recommended for human healthcare *** introducing the defected ground structure in bottom layer the lower cut-off frequencies of 2.3,4.5 and 6.0 GHz are achieved with few biological effects on radio propagation in human body *** proposed design covers numerous well-known wireless standards,along with dual-function DGS slots,and it can be easily integrated into Wireless Body Area Networks(WBAN)in medical *** WBAN links the autonomous nodes that may be situated either in the clothes,on-body or beneath the skin of a *** system typically advances the complete human body and the inter-connected nodes through a wireless communication channel.
