Abstract :
In this letter, a reconfigurable radiation pattern antenna for multiple-input-multiple-output (MIMO) applications on mobile devices is proposed. The operating frequency band of the antenna is 5.15-5.35 GHz for a wireless local area network (WLAN) 802.11a service. Each antenna is composed of a loop-and-dipole structure, as well as two switches for the reconfigurable radiation pattern, to generate a beam in three different directions. The proposed antenna is designed to have an orthogonally directional radiation pattern with high isolation and a low-correlation coefficient in the MIMO environment.
