What is the name of the tiny PCB radio connectors? (e.g. Apple WiFi/Bluetooth antenna ports)
I believe these "ultra small/sub-miniature coaxial connectors" are Hirose U.FL connectors or perhaps even W.FL. I've also seen styled occasionally as uFL instead, but the original naming convention appears to be alphabetic (U vs. W) rather than an allusion to µ for "micro" or anything. There are other similar and even compatible interconnects, for example the Sunridge MCB series claims to be "fully compatible with Hirose U.FL and I-PEX (IPEX, IPX) MHF series, 100% Equivalent.".

The receptacle on the board is actually considered the male component as it contains the center pin, contrary to my understanding in the original question. (This is also the case with e.g. SMA connectors as well, where the relevant "protrusion" is not consider the connector and its shielding as a whole, but rather of the main pin.)

Note that the durability of these connectors is typically low; I've seen data sheets specifying only 30 cycles of mating/unmating rated.
