Space Agency investigates novel analog self-steered antennas
Date:1/31/2011

Bulky present generation satellite dishes and ground terminals could become relics of the past thanks to research currently being conducted for the European Space Agency (ESA) by Queen's University Belfast's Institute of Electronics, Communications and Information Technology (ECIT) aimed at developing discrete self-aligning flat antennas.

It is hoped the work could lead to a one-size-fits all solution that could be optimised for a variety of technologies presently used to deliver satellite broadband and television to travellers as well as customers in broadband 'not spots'.

ECIT is currently working on an 18 month ESA project with the aim of developing a completely self-contained solid-state self-steering antenna that is much lighter and less power hungry than current alternatives.

The team being led by Professor Vincent Fusco plan to complete work on a 1.6GHz demonstrator - capable of providing transfer rates of 0.5Mbits/s - with a power requirement of just 2 watts. It is anticipated that the device will ultimately have the capability to operate at 20-30 GHz in order to provide much greater bandwidth.

The design currently being worked on is a 4x5 element planar array measuring 30cm by 40 cm and just 12 mm deep.

Uniquely, the circuits are entirely analogue and incorporate specially adapted phase locked loop circuits. By contrast, conventional circuits convert incoming signals to digital, process them electronically and then convert them back to analogue. This however limits their frequency, and increases their complexity, cost and power requirements.

Queen's University has a strong reputation in this specialised field, having built the world's first 65MHz self steered antenna a number of years ago. Since then, it has built a close relationship with ESA to whom it is now the main supplier of quasi-optical filters.
