Antenna engineering for the whole of the RF spectrum.
From 100 kHz to 80 GHz, from a single embedded antenna inside a sensor to a commissioned broadcast transmitter site. The work falls into the eight areas below; most engagements draw on several.
Antenna design
The core of the practice: antennas designed to suit the product, its industrial design, its host platform and its environment.
- Embedded antennas for personal and IoT devices
- Electrically small antennas — wearables, labels, security, marine AIS
- Base‑station and broadcast antenna systems
- GNSS antennas — L1, L2, E5b, multi‑band
- NFC antennas and active/passive RFID
- Antennas for GPR and specialist sensors
- Antenna siting, planning and coverage design
- Antennas for medical devices and wearables
RF systems & propagation
The platform around the antenna, and the radio path the signal has to travel.
- RF circuit design and test
- RF platform design for multi‑function devices
- Radio‑system specification review & compliance
- LF, MF and HF propagation studies & field‑strength measurement
- VHF / UHF / SHF path analysis
- Satellite link budgets
- EMC investigation and remediation
- High‑voltage RF ISM‑band applications
EMF safety & compliance
Practical ICNIRP, CEMFAW and RADHAZ advice grounded in fifty years of working around high‑power RF.
- ICNIRP compliance of base stations
- Implementation of CEMFAW
- Advice to overseas government regulators and UK local authorities
- EMF hazard investigation and remediation
- On‑site measurement of electromagnetic field intensity
- On‑site field‑strength surveys
- ICNIRP advice for landlords and property owners
Expert witness & patents
Independent technical evidence for courts, tribunals, planning authorities and licensing bodies — domestic and international.
- Base‑station siting and planning matters
- Expert witness for property owners
- Accident and engineering‑failure investigation
- Expert witness in patent litigation
- Patent drafting
- Prior‑art searching
- Responding to Examiners' search reports
On‑site services
Measurement, commissioning and diagnostic work carried out in the field, worldwide.
- Site surveys and reports
- On‑site fault diagnosis and rectification
- Installation and commissioning
- Measurement of antennas and associated equipment
- LF and MF antenna systems — 100 W to 600 kW
- Commissioning of broadcast transmitter sites
Measurement & simulation
In‑house laboratory facilities and industry‑standard electromagnetic simulation tools.
- ETS‑Lindgren 3‑D anechoic chamber, 400 MHz – 8 GHz
- Antenna pattern, gain and efficiency measurement
- Active performance of radio devices in the same band
- Network and spectrum analyser measurement
- CST Microwave Studio (full‑wave EM simulation)
- NEC‑4 (method‑of‑moments wire modelling)
Advisory & management
For SMEs in technical markets and for investors conducting due diligence.
- Reviewing prospects of companies seeking investment
- M&A advisory in wireless & RF
- Process and operations review & recommendations
- Advice on technical proposals for new products and markets
- Market assessments for new products
- Business development
Technical writing & training
Content and courses drawn from decades of standards work, research supervision and industrial practice.
- In‑company short courses on antennas, propagation & radio systems
- Training on ICNIRP & CEMFAW implementation
- Training on RF measurements and RF platform design
- Specifications, proposals, presentations
- Product handbooks and user manuals
- Standards documents

- Corrosion, metals & plastics in RF hardware
Where the work usually lands.
Most engagements involve one of the market areas below, though the practice is deliberately broad — an antenna is an antenna whether it sits in a watch, a lighthouse or a satellite.
Measurement & simulation facilities
BSC Associates maintains its own network and spectrum analysers, uses an ETS‑Lindgren 3‑D anechoic chamber for antenna patterns, gains, efficiency and active device performance in the 400 MHz – 8 GHz band, and runs CST Microwave Studio and NEC‑4 as primary electromagnetic simulation tools.
