Abstract

A multiple-input multiple-output (MIMO) antenna having a very compact size of 40×26 mm² is proposed for portable ultrawideband (UWB) applications. Two planar monopole antennas with microstrip-fed are used as the elements of the MIMO antenna and are placed perpendicularly to each other to achieve pattern diversity. Two stubs are etched on the ground plane to enhance isolation between the two elements and increase the impedance bandwidth of the MIMO antenna. Results show the MIMO antenna can cover the entire UWB band from 3.1-10.6 GHz with an isolation of larger than 16 dB throughout the frequency band.
