Spatial Multiplexing of QPSK Signals With a Single Radio: Antenna Design and Over-the-Air Experiments

Juan Ramon Mosig, Julien Perruisseau-Carrier, Mohsen Yousefbeiki, Andreas Peter Burg, Andrew Charles Mallory Austin

This paper describes the implementation and performance analysis of the first fully operational beam-space multiple-input multiple-output (MIMO) antenna for the spatial multiplexing of two QPSK streams. The antenna is composed of a planar three-port radiat ...

Multiple antenna

Julien Perruisseau-Carrier, Mohsen Yousefbeiki

A multi-input, multi-output antenna comprises an electrically conductive body, generally symmetrical about a plane of symmetry. An active port (Feed point) is located on the plane, a first parasitic port (1) is located on one side of the plane, and a secon ...
