Antenna development and RF system design

01 / From embedded antennas to antenna arrays

Antennas and antenna systems

We develop passive and active antennas for the actual installation. The PCB, enclosure, ground plane, mounting and proximity to the user are included in the electromagnetic design.

• PCB, FPC, wire, dipole, monopole, patch and broadband antennas; Vivaldi and log-periodic structures.
• Multiband, diversity and MIMO arrangements; linearly, dually or circularly polarised arrays, phased arrays and feed networks.
• Evaluation of input impedance, S11, bandwidth, radiation efficiency, realised gain, radiation pattern, polarisation and mutual coupling.

Your deliverablesAntenna geometry, integration recommendations, matching network and documented simulation and measurement results.

02 / Signal quality in the front end

RF circuits, filters and amplifiers

We design RF assemblies for the required signal levels, frequency plan and interference environment. In the receive path, we consider gain and noise figure together with losses ahead of the first amplifier.

• Band-pass, low-pass and band-stop filters; power dividers, Wilkinson dividers, couplers, duplexers and feed networks.
• Low-noise amplifiers (LNAs), active GNSS antennas, signal distribution, power supplies and protection circuits.
• Passband and stopband attenuation, return loss, gain, noise figure, linearity and intermodulation; EM and circuit simulation of parasitic effects.

Your deliverablesCircuit diagram, component selection, RF layout, prototypes and agreed measurement data for the assembly.

03 / From the antenna connector to the RF chip

RF layouts and transitions

We review and optimise the complete RF path on the PCB. A nominally 50 Ω trace alone does not guarantee a low-loss transition between components, layers and connectors.

• Stack-up, microstrip and coplanar transmission lines, reference planes, return-current paths, via fencing and layer transitions.
• Connector launches, coax-to-PCB transitions, pads, matching networks, bond connections and test adapters.
• S-parameters, insertion loss, return loss, crosstalk, resonances and coupling between radio modules.

Your deliverablesAn annotated layout review with prioritised changes, or an agreed redesign including simulation of critical transitions.

04 / Decisions before the first prototype

EM simulation and feasibility

We translate frequency bands, geometry and performance targets into a simulation model. Comparisons show which antenna position, feed arrangement or enclosure modification is technically appropriate.

• 3D full-wave simulation of the antenna, PCB, cables, enclosure and nearby conducting or dielectric structures.
• Parameter studies, field and current distributions, coupling, resonances, and circuit and network analysis.
• Comparison with measured data, evaluation of material effects and manufacturing tolerances, and documented model assumptions.

Your deliverablesFeasibility assessment, comparison of alternatives and design recommendations with clearly defined technical constraints.

05 / Validating simulation in the installed product

RF measurement and troubleshooting

We characterise antennas and RF assemblies and investigate inadequate range or reception quality. Measurements distinguish mismatch, transmission losses, interference coupling and shadowing.

• Vector network analysis, S-parameters, bandwidth, isolation and decoupling; radiation, gain and efficiency.
• Measurements of output power, gain, noise figure and IP3; comparison of integration and matching options.
• Measurements inside the enclosure and at the intended installation position; MATLAB-based automation and analysis.

Your deliverablesA measurement report covering the setup, conditions, findings and specific optimisation measures. Regulatory testing is agreed as a separate scope.

06 / Developing electronics and mechanics together

Radio modules, prototypes and integration

We develop radio PCBs and integrate antennas into existing electronics. In compact devices, we treat power supplies, digital interference sources, battery, enclosure and antenna as one system.

• SoC and component selection, circuit diagrams, RF PCB layout, matching and antenna integration.
• Prototype assembly, reflow and manual soldering, bring-up, 3D printing and mechanical integration models.
• Coexistence of LTE, Wi-Fi, Bluetooth, UWB and GNSS; prototype modifications and technical coordination with your team.

Your deliverablesFunctional prototypes, circuit and layout documentation, integration guidance and measurement data for the next development decision.

07 / Fields, coupling and shielding

Microwave engineering, EMC and power transfer

We also work beyond conventional radio modules: waveguides, resonators, high-power microwave assemblies and inductive power transfer. Our experience ranges from implant charging systems to industrial microwave applications.

• Field distribution and resonator modes, power transfer and distribution, material effects and antenna feeds.
• Electromagnetic compatibility between communication and sensing systems; shielding, leakage radiation and microwave-tight structures.
• Coupling coils and wireless power transfer; analysis of high-frequency fields and technical protection measures.

Your deliverablesField analysis and design measures tailored to power, frequency, installation environment and the agreed test objective.

08 / From a standard product to a customised variant

Product customisation and mass production

We first assess whether an existing antenna, filter, LNA or cable assembly meets your requirements. If necessary, we customise the product or develop a new version and can take responsibility for mass production.

• In-device frequency tuning, cable length and connectors, mounting, dimensions and mechanical integration.
• Design for manufacturing, material and supplier selection, manufacturing documentation, bills of materials and test strategy.
• Prototype and series production with specialist partners, incoming and final inspection, production support and technical documentation.

Your deliverablesAn approved product version with agreed electrical, mechanical and quality requirements.
