It has been conventionally assumed that a single leaky coaxial (LCX) cable only is utilized as one antenna to configure a multiple-input multiple-output (MIMO) system. In this letter, we show one single LCX cable can be used as two antennas to configure a MIMO system owing to the designed intersection angle between the different radiation directivities of both input signals. The measurement results of 2 × 2 LCX-MIMO channel quality confirm that our proposed LCX-MIMO can realize a promising channel condition over 5 GHz frequency band. It also points out that the intersection angle between radiation directivities of LCX cable needs to be considered carefully to reduce the channel degradation at the both edge portions of the LCX cable.
