OLED Based Transparent MIMO Antennas for Future 5G mm-Wave Applications.

The proposed paper offers the layout to integrate an Organic Light Emitting Diode (OLED), an optically transparent antenna for 5^th Generation wireless communication. The proposed antenna is depicted on a glass substrate which has a relative permittivity ɛ_r= 5.5 and is optically transparent and compact. The radiative patch and a ground plane are its key components that use PEC material. The suggested antenna is a chain of small isosceles triangle cells (micrometric) placed on the substrate made of glass to attain wideband characteristics. With the assistance of triangle-shaped symmetry, the theoretical optical transparency obtained is about 95%. The antenna proposed covers the band of 39 GHz from 38.19 GHz to 40 GHz with a bandwidth of 1.81 GHz. It covers a gain of 4.263 dB and directivity of about 4.65 dB. Channel capacity and the data rate get better at the transmitter and receiver end by using an 11-element MIMO antenna on the OLED structure. Simulated results show that this antenna is applicable for 5G applications due to its transparency, low profile, flexibility, and wide achievable frequency bandwidth. [ABSTRACT FROM AUTHOR]
