Unmanned vehicles provide many functions within defence and security
applications such as airborne surveillance, border patrol and tactical systems. In every case uninterrupted
communication to the control centre is vital.
Illustrated are two new, light weight, very slim, high
specification, omni-directional antennas developed by Cobham Antenna Systems (Microwave Antennas) for use on
unmanned systems. These small but robust antennas may be mounted on airborne and ground vehicles, robots and
On the left is the omni-directional blade antenna,
SBA-2.3V/1470, designed for integration into the wing of a target drone providing RF coverage behind the
platform from 2.0 to 2.5 GHz.
On the right of the photograph is an omni-directional blade antenna with
SBA-900/1249, covering the frequency 902 to 928 MHz.
The company is continually developing and
manufacturing antennas for integration into unmanned systems and for communication systems in command control
Cobham Antenna Systems Cobham Antenna Systems was formerly known as European Antennas.
Everything remains the same – same technology, same products, same single UK location, same people. The company
specialises in the design and manufacture of microwave antennas from 250MHz to 40GHz and undertake antenna
development projects. Modelling software predicts antenna specification and prototypes are tested at the company’s
on-site near anechoic test chamber to ensure specifications are met. The company has ISO 9001 certification and is
part of Cobham plc.
Cobham plc is an international company engaged in the development, delivery and support of advanced
