New development
We develop the geometry, circuit and integration around your frequency bands, installation conditions and measurable performance targets.
CUSTOM DEVELOPMENT
Multiband antennas and MIMO systems for multiple radio services.
We develop antennas for devices supporting multiple frequency bands and wireless standards. Bandwidth, efficiency and isolation are designed together with the device frequency plan.
01 / TECHNOLOGY & DEVELOPMENT
Multiple bands in one installation
Cellular, WLAN, Bluetooth and GNSS place different demands on the antenna. We assess which services can share a structure and when separate antennas provide a better system solution.
- For example, cellular bands at 700–960 MHz, 1.7–2.7 GHz and 3.3–3.8 GHz, depending on the specific product and target market.
- WLAN and Bluetooth antennas in the 2.4 GHz band; additional WLAN bands according to the frequency plan.
- Combining communication and GNSS antennas, accounting for polarisation and frontend requirements.
02 / TECHNOLOGY & DEVELOPMENT
MIMO, diversity and coexistence
Spacing alone does not ensure sufficient isolation between antennas. Geometry, ground plane, polarisation and feeding affect coupling. We evaluate alternative arrangements and their integration.
- S-parameters between antenna ports and isolation across the relevant bands.
- Radiation patterns, efficiency and realised gain of each antenna.
- Filtering, LNA design and interference coupling between simultaneously operating radio services.
03 / TECHNOLOGY & DEVELOPMENT
Optimisation from the radiator to the transceiver
We coordinate antenna position and matching with cable connections, filters and the PCB layout. This includes the losses and parasitic effects of the actual RF signal path in the development process.
- Parameter studies in HFSS and CST.
- Band-selective matching networks and comparative measurements of design variants.
- Coaxial connections, 50 Ω traces, layer transitions and controlled return-current paths.
THREE ROUTES TO THE RIGHT SOLUTION
Develop a new design. Optimise an existing solution. Customise products.
Optimisation
We analyse existing samples and documentation, identify the causes of losses or insufficient performance, and implement targeted changes.
Product customisation
We assess an existing Sevskiy solution and adapt its frequency tuning, connectors or installation. We can undertake volume production on request.
OUR APPROACH
From requirements to a tested design.
- 01
Requirements and interfaces
We clarify the frequency plan, available space, mechanical environment, supply, connections and test criteria. Existing CAD data, schematics and measurements are included in the assessment.
- 02
Design and simulation
We compare suitable concepts, design the circuit or geometry, and simulate critical electromagnetic structures and transitions.
- 03
Prototypes and measurement-based refinement
We build prototypes, measure under defined conditions and refine the design by comparing the model with the actual assembly.
- 04
Design approval and volume production
We document the agreed configuration and test plan. Production support and volume manufacturing are agreed as required.
YOUR DELIVERABLES
Technically documented and ready for the next development step.
You receive an antenna concept matched to the frequency plan, with integration requirements, matching and agreed measurement data for all ports and bands within scope.
FREQUENTLY ASKED QUESTIONS
Technical questions about working with us.
Is a multiband antenna automatically a MIMO antenna?
No. Multiband refers to operation in several frequency bands. MIMO requires multiple antenna paths, whose isolation and radiation performance must also be evaluated.
Can another band be added to an existing antenna system?
We assess resonances, available space, matching and isolation. We then decide with you whether adapting the existing structure or adding another radiator is appropriate.
