Please give your opinion on these connectors. Are these connectors useful for a 1 to 40 GHz printed monopole antenna with tapered microstrip feed width varying from 2.95 mm to 1.6 mm. Substrate material used is FR4 with 4.4 epsilon and 1.6 mm thickness. My main doubt is, are these connectors suitable for 1.6 mm thickness substrate. Please see the drawing in the data sheet and let me know your opinion.

If any one knows about other type of connectors suitable for Dc to 40 GHz for a substrate thickness of 1.6 mm please let me know about it. Thanks in advance.
for DC to 40 Ghz you should use preferably SMA style connectors or SSMA which are specified in that frequency range.
A good supplier is Huber&Suhner (but there are many others) and you may check their electronic catalog on this subject.
One way to find more about this, is to type in Google" SMA connectors Picture"(or image).. of course we all know how such a connector looks like but this way you can quickly find different suppliers and get an idea on the many shapes available..
@ Fritz Caspers Thank you sir for your reply. In a facebook group discussion and even in my previous researchgate discussion some researchers advised me to use K types connectors and not SMA connectors. I will search in google based on your advise. Thanks once again sir.
Those connectors are specified from 0 to 40 GHz so they should be fine electrically. As you can see if you look at the data sheet (have you looked at the data sheet?) the pins are too close together for the substrate you want, but if you use the connector diagonally it might fit the substrate, with only one pin to ground, and you could also cut slots in the board where the pins go so that the connector fits properly with two pins soldered to the ground. You will have to try and see what match you get, but it might work.
