Re: dipole analysis using HFSS help

hi every body , I am a beginner with HFSS , i started in designing small dipole , but i was surprised that the directivity was not as have been expected , that it is should be around 1.5 for the ideal small dipole .
the design consider operating frequency of 300 MHz and dipole of length of λ/70 = 14.28 mm , i used copper , and here is the file , so I will be thankful if any would revise it ...

Added after 4 minutes:

here is the file

Man, you should really read some tutorials!

Your integration line is way off. Your lumped port is too large and again way off.

Look at two pictures with corrected structure.

:D i am really a beginner , but have the ability to learn more about HFSS
thanks for being accurate and for the pics , i did these modifications , but still have 0.002 peak directivity , would you tell me where the worong could be ,,, Thanks in advance

actually i dont know how the source gap affects the structure , at least i didnt note that when i studied that in the books .
