The discipline everything
else here is built on.

We design and tune microwave antennas, including PCB patch arrays. We also handle system matching, filters, amplifiers and RF troubleshooting. Every figure is measured on our own bench rather than assumed.

Capability

Antenna design, matching networks,
and RF fault-finding.

R/01

Antenna design & tuning

We design and characterise microwave antennas, including PCB patch arrays. We model them in Sonnet and tune them on the bench.

R/02

Matching networks

We do system and impedance matching for antennas and front-ends. We take it to a measured return-loss and VSWR target.

R/03

Filters & amplifiers

We design RF filters and amplifiers within the <6 GHz, <20 W envelope. Above that, we advise.

R/04

RF troubleshooting

We make a stuck RF system behave. Tell us where it fails, whether range, matching or compliance. Then we instrument it, find the cause and fix the fault.

Selected work · aerospace

An antenna set for a high-altitude
pseudo-satellite (HAPS) programme.

The client got a flight-ready set of antennas. They were for a high-altitude pseudo-satellite (HAPS) research aircraft. We reviewed each design and updated it where the requirement had moved. Then we built the hardware and characterised it fully on the bench.

We advised on integration and supplied the finished antennas. The work was held to an airworthiness-grade bar. The programme is not named here, at the client's request.

Evidence

Every claim here is a measurement you can see.

You receive measured evidence for your own design, just like these plots. They come from our own bench. They show return loss, the Smith-chart match and the swept VSWR. Antenna work is only credible when it is measured.
