Abstract
A twelve element dual band multiple-input multiple-output (MIMO) antenna for a smartphone that includes a substrate, twelve single-element dual-band antennas and twelve T-shaped feed structures. The substrate has a top side, a bottom side, and four distinct side walls. The substrate accommodates twelve single-element dual-band antennas distributed along four side walls. Each single-element dual-band antenna includes a meandered slot line having two arms. Each arm is configured to radiate at specific resonant frequency. Twelve T-shaped feed structures are aligned in parallel with the twelve single-element dual band antennas and are located on the inner surfaces of the side walls, facilitating connectivity through feed ports located on the bottom side of the substrate. The twelve-element dual-band MIMO antenna array effectively radiates in a dual band at 2.4 GHz and 3.5 GHz in response to electrical signals input at the feed ports, achieving antenna diversity with good isolation.
