• Cobham plc :: Aerospace and Security, Antenna Systems, Leatherhead, RF Systems

  RF Systems Cobham Technical Services has extensive RF system design skills. This capability enables us to design bespoke solutions when a specialised component is not commercially available. Typical RF system design projects are wide and varied, ranging from the design of a modern digital communication and navigation radio for light and commercial aircraft to the design of a short range personal role radio capable of ad hoc networking for military applications. All of these projects involved a manufacturing partner at an early stage to minimise any...

• Cobham plc :: Aerospace and Security, Antenna Systems, Leatherhead, Smart Antennas

  SMART Antennas A SMART antenna can control its main radiation pattern direction and shape. This is achieved by using a fully active system in which each antenna element is controlled independently of one another. This technique requires RF control for each antenna, which introduces high complexity and cost. Cobham Technical Services has pioneered lower cost solutions that only require a single active element. A SMART antenna can improve the quality of a wireless link by providing interference suppression and/or range enhancement...
