Summary

This is a UWB helix antenna for testing receivers or transmitters. Printed on a FORM2 SLP, using copperwire for the antenna helix and a 50 Ohms feed coax. Middle conntected to one wire the ground connected to the other. One example shows measurement of a GPS antenna (MOVE2 CubeSat project).

Glue the copper using superglue on the printed skeleton. Tested for 1MHz to 3.4GHz at the moment. Useable starting from around 400MHz. Checking above 3.4 GHz has to be done.</p></div>
