Cobham Antenna Systems Microwave Antennas

British manufacturer of Directional, Sector, Omni-Directional and Ultra Wideband Antennas from 100MHz to 40GHz

Cobham Antenna Systems (Microwave Antennas) design and manufacture high specification antennas that are used worldwide. All manufacturing, testing, future technologies and development is carried out at a single location in Cheveley, near Newmarket, UK. Antenna development projects are undertaken for customers. Antennas are used throughout Military, Security, Satellite and Commercial markets, with applications including WLAN, WiFi, WiMAX/LTE, GPS, RFID, Tactical Communications/Link16, Radar, TETRA, PMR, Telemetry, Surveillance, Maritime, Broadcast and Cellular/Mobile. They are installed in many locations including airports, railway stations, weather buoys, race cars, road and rail tunnels, police helicopters, unmanned vehicles, broadcast equipment and satellite ground stations. They can be integrated into systems or designed to fit a particular application such as race car wing mirrors. All antennas are tested to ensure specification conformance.

European Antennas Ltd has been part of Cobham plc since 1999 and from 2009 is trading as Cobham Antenna Systems, Microwave Antennas

Link16 Antennas

The Link16 protocol uses the frequency band 960 to 1215MHz. Our range of extended performance broadband omni antennas has been designed for use in Link16 systems for terrestrial and naval applications communicating with airborne platforms. High gain antenna XVO7-960-1215/1120, NATO Stock Number 5985-99-7586585, covers the entire Link16 band, 960 to 1215MHz. Gain of 7dBi can double the range of a system that is constrained by output power and can achieve reception from an aircraft at 250 miles (400km) range. Other Link16 antennas and a band stop filter are available.

Electronic Warfare – Antennas to support IED Countermeasures

A portfolio of ultra wideband omni antennas has been developed within the range 100MHz to 18GHz to cover all of the bands in which high power amplifiers currently operate. New developments include multistack omni antennas featuring feed-through technology, and high gain antennas for cellular band countermeasures.

Unmanned Systems Antennas

Applications for Unmanned Systems, including airborne surveillance, video transmission, border patrol and tactical systems, all require uninterrupted communication to the control platform. As frequencies increase from L-band to Ku-band to provide wider bandwidths for higher data rates, the selection of the right antenna is critical to ensure system performance, battery-life and transmission range. Our antennas include high gain, collinear, vertically polarised omni antennas in aerodynamic foil structure; Common Data Link Ku-band omni antennas with circular polarisation and up to 4dBiC gain; spiral antennas for direction finding and directional antennas for communication between airborne towed target and the towing aircraft. Blade antennas were supplied to Cranfield Aerospace for the prototype Boeing X-48B Blended Wing Body UAV for telemetry and telecommand functions.

Radar Antennas– Portable and Fixed, Stripline and Waveguide, FMCW and Pulse

Ground radar is used for wide area surveillance equipment, such as national border control, missile guidance, marine weather, ground surveillance and asset monitoring. Ultra wideband antennas for a fixed phase array and a serpentine array have been developed.

BAE Systems commissioned a series of high specification flat panel antennas that were part of the receive and transmit antenna system for a CW Doppler Radar system at UK Aberporth Test and Evaluation Range operated by QinetiQ for the UK MoD.

C-Band Antennas for Fixed and Mobile, Military and Security, Data Links, WLAN, Telemetry, Video and Voice Links

Our range of off-the-shelf C-band directional antennas include slim, flat panel and sector antennas. With the benefit of a discreet profile where a covert or aesthetic appearance is required panel antennas can radiate with accuracy. Full radiation data is available for all antennas. Sectors have clearly defined, wide azimuth coverage that ranges from 30 to 210 degrees in the horizontal plan with profiled vertical coverage. Multi-sector arrays provide high gain and are contained in a single radome. Low wind loading and a robust construction enable our antennas to be mounted in the most demanding of environments.
