Six-port antennas for experimental verification of six degrees-of-freedom in wireless channels

Abstract
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... (More)

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. (Less)
