Antenna design
Cutting edge antenna designs to interface to the wireless world.
Our antenna designs are based on a thorough understanding of the electromagnetic principles and theory behind the EM field in the antenna. This theoretical background is coupled with the practical expertise and experience to facilitate rapid antenna development from concept, through design proving to manufacture, and supported at all stages by state of the art simulation and measurement.

Antenna simulation
Familiar in the use of industry standard tools (such as HFSS™, Matlab™, NEC, and Microwave Office™) we have the capability to model all antenna types prior to manufacture. We also use our own tool, Epsilon™, to predict installed antenna performance.
Radio propagation
Closely allied to antenna technology is the field of radio propagation. We have many radio propagation planning tools and deployment aids for communications, air traffic management and navigation, covering LF to SHF.
Channel modelling
New developments by us have made it possible to now model the two dimensional (delay and Doppler) radio channel. This is useful in modern digital communications / navigation systems where it is often the case that the signal strength is sufficient, but channel dispersion and multi-path distort the signal's symbols too much and BER is raised to an unacceptable level.
Our channel modelling tool takes a CAD model of the environment and couples this with a full phasor-vector electromagnetic solver. From this analysis parameters such as signal depolarisation, as well as delay and Doppler can all be modelled. BER can then be predicted to obtain the distorted signal at the receiver.
