In 5G communication system a high gain steerable phased array is desired. In this paper, a novel mm-Wave 256 element phased array system based on 8 element sub-arrays is presented. The sub-arrays are randomly tiled so the periodicity in the array is disrupted and significantly reduce the side lobe level (SLL). Four different rectangular sub-arrays: 1×8, 8×1, 2×4 and 4×2 are used to completely fill...
Array of field-effect transistors (FET) with asymmetric T-gates and floating electrodes fabricated on a single chip was used as terahertz (THz) detector. Nonresonant detection with strong photovoltaic response was realized due to excitation of electron plasma oscillations in the common channel of the FETs array. Voltage responsivities obtained by the array of FETs with floating electrodes surpass...
