Simulation Results

This paper deals with the optimization of MIMO antenna elements' position in modified MIMO cube for getting maximal channel capacity in indoor environment. The dependence of the channel capacity on the antenna orientation was analyzed by simulations. We have also examined the effect of the frequency dependence of the antenna system (in case of conjugate matching and nonconjugate matching) for the channel capacity. Based on the simulation results in the created and measured antenna system, the antennas were at a right angle to each other. At the two chosen different structures, we measured the antenna parameters and the channel capacity. In this paper, we present the results of the measurements which clearly confirm our simulations. We will point out the differences between the two antenna structures.

Communication Equipment

In order to improve the channel capacity of communication equipment and reduce the size of antenna, an asymmetric coplanar strip (ACS) fed four-element UWB MIMO antenna with dual band notches is proposed in this paper. The antenna has a simple structure and a compact size of 37×37 mm². The antenna consists of four modifled staircase-shaped radiation elements and four floor on the same side. The antenna elements are placed vertically without additional decoupling structure, and the isolation less than -15 dB in the working bandwidth of 2.9-10.6 GHz can be obtained by using polarization diversity. In addition, the antenna has the notched characteristic of WiMAX and WLAN band. The antenna has good gain and low envelop correlation coefficient (ECC), and the simulation results agree with the measured results, which indicates that the antenna is suitable for UWB system.
