Hi all :

which is the best way for feeding a Log periodic toothed planar antenna in HFSS when we simulate it for using in UHF frequences between 300 & 3000 MHz.

Hi, I think, that coax feed is best. Now, I'am modeling of log periodic planar antenna for 3,1-10,6GHz and I receive good results. I compare results with results from WIPL
