The invention discloses shared-aperture dual-band dual-polarized antenna array and communication equipment. The antenna array comprises a first dielectric substrate, a second dielectric substrate, a third dielectric substrate, a fourth dielectric substrate, and a fifth dielectric substrate. The first dielectric substrate, the second dielectric substrate, and the third dielectric substrate constitute a dielectric substrate group. The dielectric substrate group is provided with a low-frequency antenna element and four high-frequency antenna elements. The low-frequency antenna element is loaded with a filtering structure. The low-frequency antenna element and the high-frequency antenna element are fed by coaxial lines. The fourth dielectric substrate and the fifth dielectric substrate form a dual-function metasurface. When the dual-function metasurface is used as an artificial magnetic conductor reflector, the radiation of the low-frequency antenna element is enhanced in a low profile, and when used as a frequency selective surface, the electromagnetic scattering of the low-frequency antenna element in the high-frequency band is suppressed. Compared with the existing solutions, the present invention is more compact, and maintains high cross-band isolation and stable radiation patterns in dual bands.

The present disclosure is a system comprising at least three electronically steered antennas arranged so that there is a baseline difference of a predetermined amount of wavelength between the centers of the antennas, typically configured as an obtuse or scalene triangle, where the distance between each antenna on an array is selected to provide the required accuracy and precision, the array having a timing circuit to ensure that the beam of each antenna is steered to the same azimuthal and elevation coordinates in space simultaneously. This enables the three electronically steered antennas to operate as an interferometer to determine a bearing to a target to ultimately determine the location thereof. The electronically steered antennas enable the system to be mounted on a platform in a small package that was previously difficult for traditional interferometers.
