Performance enhancement of the compact defected ground structure multi-port MIMO antenna with modified FSS structure for 5G NR mm wave applications

A Compact millimetre-wave multiple-input multiple-output (MIMO) antenna is presented for next-generation 5G wireless communication. The antenna is designed on a Rogers RT/Duroid 5870 substrate having a thickness of 0.79 mm with a relative permittivity of about 2.33 and a low dielectric loss of nearly 0.0012 to obtain h...
