I have tried to measure a fabricated patch antenna which has theoretically multiband ranging from 1 GHz to 8 GHz, but when I tried to measure it through NanoVNA it barely shows the result from 1 GHz to 4.4 GHz. Is there a limit in the NanoVNA or am I just making a mistake every time?

2Which NanoVNA? There have been several versions and upgrades since the first NanoVNA came out. – JRE Apr 02 '22 at 16:58
