Hi all,
I Am currently working an a design, featuring an RFM22B 868MHz module, transmitting at upto 20dBm.
The PCB i am designing fits into two slots in a aluminum profile, and the in bottom i will mill a slot antenna at 164,3mm. (See attached photo)
Tests indicate a feedpoint at 1/20 wavelength, on each side of the slot.
My problem is, how to establish a good RF connection from the PCB to the Aluminium surface, preferably something spring-like or pointy mountable on the pcb, so the pcb can be pushed into the slot, fixed, and has a good rf connection to the slot
Any ideas, or experience with "RF-to-aluminum-enclosure-connections" would be highly appreciated
Best Regards
Morten Opprud
