Sammanfattning

In 2001, a paper published in Nature by Andrews et al postulated the use of six co-located antennas, namely three electric and three magnetic dipoles, to achieve up to a six-fold capacity increase in wireless channels, relative to that of a single antenna. In other words, six degrees of freedom (DOFs) can be supported in a wireless channel with co-located six-port transmit and receive antenna arrays. However, due to the complexity in designing and measuring such a six-port antenna, to our knowledge, no experimental verification has yet been successfully performed. In this paper, we present six-port antennas that are designed and fabricated for experimental verification of the six DOFs hypothesis at the 300 MHz band. For the compact six-port receive array with dimension of 0.24 wavelength(or lambda)^3, the highest pattern correlation between any two ports is 0.32 and the total antenna efficiencies are similar, at approximately 25%. The corresponding dimension, correlation and port efficiencies for the larger six-port transmit array are 0.75lambda^3, 0.13 and 75\%, respectively.
