Square Kilometre Array (SKA), the next generation radio telescope, is under development. Mid-Frequency Aperture Array (MFAA) Consortium had been established to develop and design the Aperture Array technology for SKA.
Octagonal Ring Antenna (ORA)
ORA developed at the School is one of the candidate antennas for the MFAA technology. The ORA is
- a novel and potentially breakthrough technology using a planar, easily fabricated, structure
- designed to be a low cost, low loss, wideband array
- dual polarised and operates at wide scan angles.
The research activities involve development of
- broad band large scale low noise phased array antennas
- low noise front-ends for radio astronomy application
Applications of ORA are
- radar industry
- radio astronomy
- improved high data rate communication
- multifunctionality of services
- higher resolution imaging for small objects.
The properties of the patented ORA include:
- Simple planar structure using low cost manufacturing techniques
- Stable cross polarisation
- Wide scan angle with a stable scan pattern
- Differential or single-ended feed
- Wide Band Array Antenna patent-GB2469075A, WO2010/112857A1
The project is run in collaboration with
SKAO, ASTRON, SELEX Galileo, Trackwise, Sarentel, Cambridge Consultant, KLAASA.
