MFAA development - the testing of mounting options

Submitter: Martijn Brethouwer
Description: Sometimes, if you want to test your ideas, the best way is to grab your prototype, hook it up to some measurement equipment, and tap it with your hand.

In this case, we were testing what would be the best option to mechanically connect our antennas together. We like to have some flexibility in this connection to allow for production tolerances and material deformation due to temperature changes. However, it must remain sturdy enough to retain a good electrical connection.

We verified this by measuring the transfer function between two antenna elements. We tried different methods of connecting these two elements together and verified what influence movement and vibrations had on the transfer function. The ideas which have survived this basic test are now being developed further and will of course be subjected to more "scientific" testing.
