Abstract
A laminar phased array has a first sub-array configured to operate in one of a receive mode with a first polarity and a transmit mode with a second polarity, and a second sub-array configured to operate in one of a receive mode with the second polarity and a transmit mode with the first polarity. The first polarity is physically orthogonal to the second polarity. The array also has a controller configured to control the first and second sub-arrays so that they operate together in either 1) a receive mode or 2) a transit mode. Accordingly, both sub-arrays are configured to operate at the same time to receive signals in the first and second polarities when in the receive mode. In a corresponding manner, both sub-arrays are configured to operate at the same time to transmit signals in the first and second polarities when in the transmit mode.
