New development
We develop the geometry, circuit and integration around your frequency bands, installation conditions and measurable performance targets.
CUSTOM DEVELOPMENT
Broadband and UWB antennas for a wide usable frequency range.
We develop broadband antennas for wireless, measurement and positioning systems. Vivaldi, log-periodic and planar structures are designed for bandwidth, directivity, polarisation and installation requirements.
01 / TECHNOLOGY & DEVELOPMENT
Choosing the antenna type for the application
A broadband receiving antenna, a directional measurement antenna and a compact UWB antenna have different priorities. We design the geometry around the required frequency range and spatial coverage.
- Tapered-slot and Vivaldi antennas for broadband directional solutions.
- Log-periodic antennas and planar broadband structures.
- Linear, dual or circular polarisation according to system requirements.
02 / TECHNOLOGY & DEVELOPMENT
Broadband feeding and integration
The coaxial connection and transition to the antenna structure must work across the entire operating range. We account for transmission-line routing, balancing and the effects of the cable and mounting arrangement.
- Broadband impedance control and matching.
- Coax-to-PCB transitions and grounding.
- Coupling to the device enclosure and changes in the radiation pattern across frequency.
03 / TECHNOLOGY & DEVELOPMENT
Checking frequency-dependent performance
We define the usable bandwidth through the agreed performance criteria. A low S11 over a wide range alone does not establish whether gain, polarisation and radiation pattern suit the application.
- Matching, efficiency and realised gain across the frequency range.
- Radiation patterns and polarisation at selected test frequencies.
- For UWB applications, group delay and impulse response can be assessed as an additional agreed measurement scope.
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 a broadband antenna design with a defined operating range, feed and integration guidance. We also assess whether an existing Sevskiy broadband antenna can be adapted.
FREQUENTLY ASKED QUESTIONS
Technical questions about working with us.
Are broadband and UWB the same thing?
Broadband describes a large usable frequency range. UWB refers to a particular system application or signal bandwidth. The antenna must suit the frequency plan and requirements of the specific UWB system.
Can you adjust directivity and polarisation?
Yes. We design the radiator geometry, feed and, where appropriate, multiple antenna elements accordingly and evaluate performance across the required frequency range.
