Wideband microstrip MIMO antenna for millimeter-wave applications

This paper presents a wideband planar antenna based on microstrip structure. By loading shorted vias on the specific location of the microstrip line, and carefully choosing the size of feeding line, good impedance matching and high peak gain can be achieved. The multiple-input-multiple-output (MIMO) antenna for millimeter-wave (mm-wave) applications is also designed. The simulated results of the proposed MIMO antenna show good performance in impedance bandwidth, isolation, peak gain and radiation patterns.
