Abstract
In an embodiment, an antenna unit for an antenna array allows shifting the phase of a radiated or received signal without the need for a phase shifter, and includes an antenna element, switching devices, and signal couplers. The antenna element includes at least one section and signal ports each electrically isolated from each other and from each of the at least one section. The switching devices are each configured to couple a respective one of the signal ports to one of the at least one section in response to a respective control signal, and the signal couplers are each configured to couple a respective one of the signal ports to a respective location of a respective transmission medium.
