摘要The geometrical shape of antenna arrays for maximizing the average channel capacity of the system in a multiple-input multiple-output link is investigated. The optimum element spacing of the transmitting antenna is also included. The frequency responses of transceiver antenna with different element spacing are computed by ray-tracing techniques, and the channel frequency response is further used to calculate corresponding channel capacity. The transmitter is set in the center of the indoor environment and the receivers are with uniform intervals distribution in the whole wooden table. Linear shaped array, L shaped array, T shaped array and rectangular shaped array with non-uniform inter-element spacing are investigated for both line-of-sight and non-LOS scenarios. The optimal element spacing of antenna for maximizing the channel capacity is searched by particle swarm optimizer. Numerical results have shown that our proposed method is effective for increasing average channel capacity. It is also found that L shaped array has the highest channel capacity and the improvement ratio for rectangular shaped array is the largest.
