Yes I used this in one of my Sigfox designs, but I haven’t done extensive lab testing other that “it works” for me and test sites. I expect the performance to be similar on LoRa.
Texas Instruments is also shipping thousands of units using this design on their new 868/915Mhz + Bluetooth LE Launchpad: http://www.ti.com/tool/launchxl-cc1350
Having said this PCB antenna design is fussy and depends on many factors, ie it only takes the fiberglass fibers that make up the PCB structure being aligned differently to affect performance. It’s also true that our friends at HidNSeek have achieved some impressive range records - last one 900 Km, likely harnessing tropospheric ducting - using a cheap, small and rather easy to mount helical antenna like below, so make sure you consider all options.
