Typical optimization activities:
- Antenna placement studies
- Radiation efficiency improvement
- Range optimization
- SAR-aware antenna design
- Multi-radio coexistence analysis
System Design
Integration & system design
Antenna performance depends on the complete system, not just the antenna itself.
Customer benefits:
- Reduced integration risks — RF, PCB and mechanics developed together
- Improved wireless performance — optimized system-level behavior
- Faster validation cycles — issues identified early through simulation
- Reduced redesign costs — informed design decisions before prototyping
Practical implementation:
- Co-design with electronics, RF and mechanical engineering teams
- 3D CAD model integration into antenna simulations
- Complete antenna subsystem development
- Mechanical and industrial design collaboration
- Ground plane and enclosure optimization
Measurement
Antenna measurement and verification
A design is only as good as the measurement that confirms it. Our antenna laboratory characterises a design against its specification — and when a design misses its target, the same measurements show whether the loss sits in the antenna, the matching, the ground plane or the enclosure.
Antenna characteristics we measure:
- S-parameters — return loss, VSWR and port-to-port isolation
- Gain and full 3D radiation patterns
- Radiation efficiency and total efficiency
- Axial ratio for circularly polarised antennas
- Passive characterisation of a bare antenna or a fully assembled device
- Active over-the-air performance on live cellular links — TRP and TIS
Collaboration
Collaboration in product development
Antenna design is tightly connected to overall product performance.
Every project starts with the specification you bring us. We review it together, say plainly which requirements are reachable and which are in tension with each other, and agree what the final product should be before any design work begins.
Our operating model:
- Close collaboration with RF, electronics, PCB and mechanical teams
- Iterative simulation, prototype and verification cycles
- Fast design reviews and optimization workshops
- Transparent reporting and design documentation
- Production and lifecycle support
Tools & Tech
Tools and methodologies
We utilize advanced simulation, measurement, and verification tools throughout the development process.
Tools include:
- CST Studio Suite electromagnetic simulation platform
- 3D CAD model import and co-design workflows
- Satimo SG64 antenna measurement system
- Passive antenna testing up to 6 GHz
- Active cellular antenna testing (TRP/TIS)
- Vector network analyzer for S-parameter and impedance measurement
- LPKF circuit board milling for in-house antenna prototypes
