Accredited Antenna Performance Testing
At EMC Technologies, we provide accredited antenna reception test services to verify real-world antenna performance, efficiency and radiation behaviour across a wide range of wireless and RF-enabled products.
Testing is conducted in controlled laboratory environments using precision measurement equipment to ensure repeatable, defensible results suitable for design validation, troubleshooting and regulatory support.
Our experienced RF engineers work with manufacturers, product designers and system integrators to assess antenna performance at both component and integrated product levels. This supports applications across telecommunications, IoT, industrial electronics, defence and consumer devices.
Core Antenna Parameter Measurements
Accurate antenna characterisation is critical to wireless performance. At EMC Technologies, we carry out detailed antenna reception test measurements to assess key electrical and RF parameters that directly affect range, reliability and compliance.
Core measurements include:
- Return loss and VSWR
- Antenna efficiency and total radiated power
- Gain and directivity
- Impedance matching across operating frequency bands
At EMC Technologies, testing is performed using calibrated instrumentation inside controlled RF environments to ensure external interference does not influence results. Where required, testing can also help to support design optimisation or fault investigation for underperforming wireless products.
Radiation Pattern and Polar Plots
Radiation pattern analysis provides accurate insight into how an antenna transmits and receives energy in three-dimensional space. Our expert team of engineers produce accurate radiation pattern measurements and polar plots using precision rotation systems inside a certified antenna test chamber.
These measurements help to identify:
- Directional nulls and coverage gaps
- Unwanted radiation lobes
- Performance degradation caused by enclosure materials or PCB layout
Radiation pattern testing is valuable where antenna placement and orientation of surrounding components may influence RF behaviour. Results are often supplied in clear graphical formats suitable for engineering review and technical documentation.
State-of-the-Art iOATS and Anechoic Facilities
At EMC Technologies, all antenna testing is carried out in our advanced RF facilities, including fully compliant iOATS sites and specialised anechoic chamber environments designed to eliminate reflections and external RF noise.
Our facilities include:
- Full-sized RF anechoic chambers for radiated measurements
- Shielded environments for low noise testing
- Chambers configured to support integrated device testing
Where acoustic isolation is also required for specific measurement conditions, testing can be performed within an anechoic acoustic chamber configuration as part of controlled RF assessment processes.
Our facilities ensure accurate, repeatable data suitable for development and formal reporting.

FAQs about Antenna Performance Testing
Why do I need to measure return loss in an anechoic chamber?
An anechoic chamber allows return loss to be measured without external reflections or interference. This helps to confirm the antenna is correctly matched and helps avoid reduced range, poor efficiency and compliance issues caused by reflected signal power.
Can you measure the performance of an antenna integrated inside my product's enclosure?
Yes. At EMC Technologies, we routinely perform antenna reception test measurements on antennas integrated within final product housings, accounting for enclosure materials, internal components and mechanical constraints.
What are the metrics of antenna performance?
Common metrics of antenna performance include gain, efficiency, radiation pattern, return loss, VSWR and bandwidth. These metrics collectively determine wireless range, stability and overall RF performance.
How to determine antenna efficiency?
Antenna efficiency is determined by comparing the power accepted by the antenna to the power radiated. This measurement is carried out within the controlled RF environments such as anechoic chambers using calibrated reference methods.
