Abstract

A MIMO CPW-Fed slot antenna is presented for sub-6 GHz 5G applications. This antenna operates at the lower band which extended from 4.2 to 5.2 GHz. The overall MIMO dimensions are 21.6 × 42.2 mm2. The proposed MIMO consists of two identical antennas; each one is a rectangular slot excited with rectangular tuner. A triangle shape and two shunt stubs are connected to the rectangular slot to reduce the antenna size. A unique asymmetric electromagnetic bandgap (EBG) structure is utilized beside polarization diversity for coupling reduction. The element to element isolation is improved to vary from (-26 dB to -50 dB) in case of 0.1 λ0 edge to edge spacing. The simulated and measured results confirm that the proposed antenna is suitable for sub-6 GHz 5G applications. The envelop correlation coefficient is less than 0.025 over the operating band and the diversity gain is almost 10 dB showing satisfactory performance.
