This paper presents a reconfigurable low profile ultra-wideband (UWB) phased array, having as much as 14.1:1 instantaneous bandwidth suitable for UHF to millimeter wave applications, with unprecedented integrated digital beam-forming capability across the entire bandwidth. To realize spectrum efficiency, aperture reconfiguration is also proposed. That is,(More)
We propose a new class of transceivers for secure communication and interference mitigation, operating over large bandwidths on the order of 10GHz. Specifically, a novel coding approach that combines frequency and code multiplexing is proposed. Equally important is power and hardware reduction by implementing a low power on-site coding with beamforming. The(More)
We proposed a novel reduced hardware receiver architecture with on-site coding. The proposed system offers a substantial reduction in the number of ADCs, and hence, fewer FPGA I/O pins. This results in a significant SWAP-C reduction, making digital beamforming with multiple concurrent beams more practical for large arrays. The proposed system was(More)
