SAR definition

Specific Absorption Rate (SAR) enables to quantify Human exposure to electromagnetic fields radiated by wireless devices held in close proximity to the user.

Part of the energy transported by electromagnetic fields radiated by a wireless device for example is absorbed by the human body. International guidelines define limits and measurement standards describe protocols for assessing SAR.

SAR limits

 
There are two different SAR calculation methods (human body tissue):
- Over 1g
- Over 10g

Example
SAR 10g is used in Europe (IEC) and SAR 1g in the US (FCC). Regions and countries among the world are generally referring to one of those two methods.

Wireless applications evolutions

Antennas are everywhere around us and 5G is even amplifying the trend. The tendency is leading to a huge multiplication of antennas in our daily life. More than ever, measuring fastly and accurately antenna radiations is important. 
This is even more strategic today, at a time when Human exposure to EMF is becoming a societal concern.

How the industry can address this strategic topic ?
To understand antenna radiations, you need to measure them. The more you get accurate and complete physical informations, the more you can understand and masterize the topic. Regarding Human Exposure to EMF, the issue is that historical measurement technology is not capable anymore to accurately measure the new, complex and challenging signals of the new radio, such as 5G.   

The solution
The D-Phase core technology by ART-Fi has been designed for solving this issue. D-Phase is based on an innovative concept merging hardware and software inventions, exclusively relying on the laws of physics. The law of physics are the best way to address the new radio measurement challenges. 
The antenna testing segment has started to move forward and the industry is starting to benefit from this opportunity.
 
As the founder of the D-Phase technology and after 10 years of investments, ART-Fi furnishes a brand new range of solutions making possible to test up to 100% of the devices directly in the production line.
