A Foldable and Reconfigurable Monolithic Reflectarray for Space Applications

Design of a Reconfigurable Reflectarray Unit Cell for Wide Angle Beam-Steering Radar Applications

A reconfigurable aperture-coupled reflectarray element is proposed for the realization of beam steering antennas, suitable for radar applications. Each reflectarray element is coupled to a microstrip line, which is loaded by a single varactor diode acting as a phase shifter element, thus providing a continuously variable reflection phase. A reduced size reflectarray unit cell is properly design...

Monolithic Analogue Reconfigurable Devices

This paper presents differential frequency-to-voltage (F/V) and voltage-to-frequency (V/F) converters employing single CMOS Field Programmable Analog Array (FPAA) device. The proposed electronic circuits are based on charge-balance conversion method. The F/V converter basically consists of analogue comparator, differentiator that detects the rising and falling edges of the shaped waveform, volt...

Monolithic Microwave Integrated Circuit (MMIC) Technology for Space Communications Applications

A Reconfigurable Data Path Processor for Space Applications

This paper introduces a reconfigurable processor under development, and targeted to an ultra-low-power, radiation tolerant CMOS process. The architecture has been selected to implement a synchronous pipeline computational model. The highly-parallel, reconfigurable data path emphasizes agile data flow instead of agile control flow for data-intensive, streaming processing for spacecraft.

A software radio-based reconfigurable transponder for space applications

A novel approach to space communications is represented by the Software Radio (SR) concept, a new technology currently deeply investigated by the scientific community, especially for wireless applications such as mobile communications or wireless network access. The SR approach leads to the definition of a new generation of radio equipment, whose communication functions are almost completely de...
