FREQUENTLY ASKED QUESTIONS

What makes an antenna radiate well?

​

Antennas are the opposite of a controlled-wave, like a transmission line. To make a bad antenna, make a good transmission line. To make a good antenna, make a bad transmission line. This means we want to spread the currents from the ground plane instead of tightly couple them. Get the antenna away from the ground plane and other metal objects and ensure the antenna and ground plane are a reasonable size compared to a wavelength. 

Why is my device failing PTCRB/CTIA testing?

​

Radiated spurious emissions (RSE) - RSE has failed due to poor RF to power supply isolation, too much RF pickup of non-linear devices or poor filtering or antenna matching. 

​

Over the air testing (OTA) - Total Radiated Power (TRP) has failed due to a poor transmission line design, too many miscellaneous losses, poor antenna matching or a poor radiator (antenna). Total Isotropic Sensitivity (TIS) has failed due to desense of the receiver, which is caused by noisy analog/digital circuits.

​

How can I improve my wireless performance?

​

Wireless performance starts with the antenna. The better the antenna, the more range and reliability one can expect from any wireless system. Secondly, more transmit power is an easy way to get more wireless range as long as the link isn't too asymmetrical. Thirdly, better receiver sensitivity will ensure good downlink performance and the IoT device behaves as expected from the link margin provided by the Friis Equation.
