how do you connect a SMA Female PCB Panel Edge Mount Plug with 4 Pins Stand Straight Connector to a Arduino?

Could you explain why you would want to attach an antenna connector to an Arduino?

i don't good internet at home, so i want to make a Radio that does not require internet

Put the antenna on your radio

i want to make a Radio that uses a arduino pro mini and be a offline radio using the SMA Female PCB Panel Edge Mount Plug with 4 Pins Stand Straight Connector like this one:

but with modifications

Do you have all the other parts connected?

A straight piece of wire works fine as a receiving antenna, about 74 cm for the FM band.
No PM's please.

no i don't have all the other parts connected because i want to know if it will work or not, i don't want a piece of wire as it can break easily and i was thinking of putting this to act as an antenna

It won't work without ALL the other parts, antenna or no antenna.
No PM's please.

SMA connectors are usually associated with connecting cables operating at relatively high frequency - like HF and microwave frequency. It will work nicely at lower frequencies. But ----- a nice question is --- why do you want to connect such a component to an arduino?

Just so the OP doesn't get the wrong idea -- "RF", an abbreviation of "Radio Frequency", is a term that refers to ALL frequencies of electromagnetic energy below Infrared -- a frequency, such as 100kHz, is RF, but I wouldn't call that a "relatively high frequency".  So, it's misleading to associate "relatively high frequency" with "RF".  RF can also refer to relatively low frequencies.

Obviously an XY problem.

A solution is given (connect an antenna) but there is no information whatsoever on the problem, or how this solution is even a remotely possible solution to the perceived problem.
