Abstract
A partitioned aperture array antenna. The novel antenna includes a first subarray having a first number of antenna elements equipped with transmit functionality and a second subarray having a second number of antenna elements equipped with receive functionality, wherein the first and second numbers are not equal and the first and second subarrays have at least one common antenna element. In an illustrative embodiment, the first subarray includes a transmit circuit coupled to each antenna element in the first subarray for controlling a relative transmit phase of the antenna element to steer an overall antenna transmit beam, and the second subarray includes a receive circuit coupled to each antenna element in the second subarray for controlling a relative receive phase of the antenna element to steer an overall antenna receive beam.
