Abstract

A transmit antenna system configured to steer an electromagnetic beam includes an antenna and an electronic steering module. The antenna includes a first electric antenna element oriented parallel to a first plane, a second electric antenna element oriented orthogonally to the first electric antenna element and parallel to the first plane, and a first magnetic antenna element oriented orthogonally to the first electric antenna element and the second electric antenna element. The electronic steering module is in electrical communication with each of the first electric antenna element, the second electric antenna element, and the first magnetic antenna element. The electronic steering module includes at least one amplifier configured to control the amplitude of a current to each of the first electric antenna element, the second electric antenna element, and the first magnetic antenna element.
