KA-BAND PHASED ARRAY ANTENNA TILE FOR SMALL SATELLITES (ARTES AT 5E.022)

Description

The objective of this activity is to design, manufacture and test a prototype of a 10x10-cm tile integrating all elements of a Ka-band transmit or receive active phased array antenna. Targeted Improvements: Enabling a Ka-band phased array antennas for nanosatellites, demonstrating up to four single-polarisation beams. Description: While at the beginning of the millennium CubeSats were mostly considered educational projects allowing students to gain experience of a full satellite development cycle, today, with the evolution of technology, the increase of both the maturity and size of CubeSats, as well as the miniaturisation of electronics, CubeSats canbe considered low-cost platforms for providing commercial telecommunication services. In order to build flexible telecommunication services, the development of modular active phased array antennas ready to be accommodated on CubeSats with different form factors would be extremely beneficial for manufacturers and operators. Despite some first attempts, no commercial product within the ESA Member States exists to meet such a need. This activity will develop a breadboard that consists of separate-aperture transmit and receive phased array active antenna tiles suitable for low-Earth-orbit missions on CubeSat platforms. The design shall be modular, with the tile being 1U, such that a customised solution can be offered without non-recurring costs to best fit customer-specific requirements. Furthermore, the design shall be flexible enough to accommodate the antenna modules on either the large or the small face of theCubeSat, with the associated requirements on overall thickness to fit in the deployment system. The antenna shall be developed using technologies enabling a high level of integration and low power consumption, such as SiGe or even CMOS, maximising the integrationof amplifier, filter and analogue beamformer functions of a number of radiating elements in a single Monolithic Microwave Integrated Circuit. Procurement Policy: C(2) = A relevant participation (in terms of quality and quantity) of non-primes (incl. SMEs) is required.
