Investigation of a Multifrequency Reconfigurable Phased Array Antenna
Abstract
The Government has a future requirement to operate several systems simultaneously from a common aperture. A technique has been studied to accomplish this objective by using a control circuit behind each element of the array. The control circuit consists of an arrangement of filters, an attenuator, and a phase shifter. The filters are used to partition the reconfigurable aperture into several simultaneously operating antennas. The attenuator provides independent illumination control while the phase shifters are used to scan individual antenna beams. A laboratory model of a reconfigurable array was designed, fabricated, and tested. The results show that the proposed control circuit provides the desired aspects of reconfigurability.
