چکیده
This paper presents a wideband eight-port multiple-input-multiple-output (MIMO) circularly polarized antenna system for mm-wave applications. The proposed element is an L-shape microstrip line with series fishtail stubs on one side. spacing between these adjusted to be guided wavelength at the center frequency. These are used cancel anti-phase magnetic currents enhance radiated fields from line. A 90° phase difference of two arms obtained by shifting feeding point corner eighth wavelength. introduces required circular polarization. covers frequency range 27.5 up 31 GHz, which suitable N261 5G-band cover 28.35 GHz. elements arranged four corners rectangular substrate configure MIMO system. Different parameters this investigated using numerical simulation and verified experimental results.
