Simulation of Yagi antenna with HFSS

hello everybody
is there anybody here to help me and solve my problems in simulation a Yagi antenna which i simulated with this specifications :
i have simulated with 7 cylinder( 7 element)

1) Frequency : 300MHZ in VHF Band
2) The Reflector length : 0.51landa
3) Spacing between reflector and Driven element(Dipole or feeder) : 0.25landa
4) length of Driven element (Dipole) : 0.47landa
5) length of Director element : 0.406landa,but i put the different length for these 5 director
6) Spacing between driven element and Director : 0.36landa
7) spacing between Directors : 0.34landa
.......Spacing between all director are thew same and fixed
8) radius of cylinder : 0.03landa
number of Element : 7
i add HFSS link right here:
**broken link removed**

hellow..may i ask the Thread starter about the books that contains yagi equation..
i search all the book and gains nothing,,

the equation of the vswr, gain, and something else

Hi
Book "Antenna Theory and Design - Stutzman. Varren L" has a distinct part for Yagi Antenna which you can use it and it is explained completely.
