Investigation of planar and conformal printed arrays for MIMO performance analysis

Abstract

MIMO channel capacity of printed arrays with dipole elements is analyzed. A MIMO channel model based on electric fields is used. The effects of mutual interactions among the array elements through space and surface waves are included into the channel matrix using a fullwave hybrid Method of Moments (MoM)/Green's function technique in the spatial domain. MIMO capacity of printed arrays is then compared with that of free standing thin wire dipole arrays. Results show better performance of printed arrays.

Correlation Effects on the Mimo Capacity for Conformal Antennas on a Paraboloid

“…Conformal antenna arrays are utilized in airborne and space vehicles and also find applications in situations where surface adaptation is required (e.g., environmentally friendly cellular base stations) or flexible substrates [13][14][15]. Several conformal antennas have been suggested for MIMO use focusing only on mutual coupling but without any capacity calculations [16][17][18][19][20].…”

Optimization of linear wire antenna arrays to increase MIMO capacity using swarm intelligence

“…Physical limitations in portable devices force multiple antennas to be spaced closely which result in the generation of considerable amount of mutual coupling between antenna elements. The effect of mutual coupling on these systems is significant and can not be neglected [4][5][6][7][8][9][10][11][12][13][14][15]. Thereof in this study, MIMO capacity is calculated using a channel model with electric fields (MEF) which is proven to be capable of analyzing array characteristics such as electrical and geometrical properties in detail [15].…”
