Thats stubm balun, it may be directed downward or upward, I have no idea what the difference in operation is. Only klow that is to phase shift. (My version in previous page was tunable)

Open side pointing up (the direction of the Energy you DON'T want coming through the Shield of Coaxial) imho The confussion comes from the rubber duckie pointing DOWN (open end) cause it is ACTING as a Quarter wave and ground plane to obtain a HALF WAVE dipole...

Dear Sir,

After a long gap, I revisited this website and designed an dual band 2.4GHz and 5GHz omnidirectional antenna based on approximate online dimensions. I attempted to set up a wave port, but encountered meshing issues.

I have attached the design file. Could you kindly help simulate the antenna?

Thanks in advance.
