The proposed MIMO antenna exhibits a wideband frequency range from 1.8 to 2.6 GHz, equivalent to bandwidth of 54.5%, while simultaneously achieving an isolation of −14 dB. Moreover, the proposed antenna demonstrates nearly omnidirectional patters, acceptable power gain, good envelope correlation and channel capacity loss.

Book 2018G communications, which already has the 5G drive in place with prominent scenarios and use-cases emerging. They examine these, and put in place the challenges that lie ahead for antenna design, particularly in mm-Wave design. The book provides a reference for practicing engineers and under/post graduate students working in this field.

Einleitung und Problemstellung, can be tuned to achieve 8% bandwidth. Likewise, by optimising the geometry parameters of the parasitic element, the upper operating frequency band can reach the required 12.2% bandwidth. Both the computed and measured features of the present antenna are in good agreement.
