Abstract
A compact slot multiple-input multiple-output Antenna (CSMA) for smartphones with metal housing is proposed in this paper. The antenna has a slot radiator shared between two input ports and a T-shaped defect-ground slot (DGS) for decoupling. A function for selecting the best dimensions of the DGS for optimum decoupling is derived using the transmission theory. The CSMA antenna is designed using simulation to operate in the 2.4-GHz wireless-area-network (WLAN) system and then fabricated for measurement. Measured results show that the antenna has an impedance bandwidth (IMBW) of 2.4–2.48 GHz, mutual coupling from −19 to −29 dB and envelope-correlation coefficient (ECC) below 0.0867 within the IMBW. The antenna is very easy to fabricate and is a potential candidate for the MIMO smartphones antennas with metal housing.
