As part of my job, I designed and built an RF chamber to conduct independent experiments and testing, focusing on determining transmission (Tx) and reception (Rx) power. The chamber provides a controlled environment, minimizing external interference and ensuring accurate measurements. This setup allows for precise performance evaluation of RF components, optimizing system efficiency and reliability.
The purpose of constructing the RF chamber is to establish a reliable reference for calibrating other testers.
I designed and 3D-printed the smooth parts necessary for dismounting and inserting a capsule in the best and most accurate way.
I have using an omni antenna because it provides uniform 360-degree coverage in the horizontal plane, making it ideal for applications where signals need to be transmitted or received in multiple directions without requiring precise alignment.
I use a TESCOM cell because it was available to me, and doesn’t take up much space:
And the testers results:
The results showed a deviation of no more than 1 dBm between different capsules.
