Background/Objectives: A novel Coplanar Waveguide (CPW) fed Multiple Input Multiple Output (MIMO) ultrawideband (UWB) antenna with a size of 26mm x 40mm x 0.8mm is proposed for portable device applications. Methods/Statistical Analysis: Two monopole elements with CPW fed are the elements of MIMO antenna and are placed perpendicular to each other to obtain pattern diversity. To enhance the isolation between elements and to improve impedance bandwidth, a long protruding ground stub is etched on the ground plane. Findings: The proposed antenna can cover the frequency band from 2.3-12.5 GHz with isolation more than -20 dB over the entire frequency band. A peak realized gain of 4.5 dBi and efficiency of more than 90% is achieved through the proposed antenna model. Applications/Improvements: High isolation of more than -20 dB is obtained from 2.3-12.5 GHz. The proposed antenna is good candidate for portable device applications.
