Hi All,hrxvdtzd hrxvdtzd hrxvdtzd hrxvdtzd hrxvdtzd hrxvdtzd Someone has told me that it is impossible to place the Helical Antenna for EM simulation because it is hard to model the helical structure. Is the statement true or not ?hrxvdtzd hrxvdtzd hrxvdtzd hrxvdtzd hrxvdtzd hrxvdtzd Best Rgs |

| 1 | scuzt | You can simulate the helical antenna by the NEC or SuperNEC software (anyway I have seen the corresponding SuperNEC example), but I don't know how it will be accurate. With responce, Kit-the-great |

| 2 | booksir | But, how can we start if we have choosen some common ISM band frequency in US (900MHz, 1900MHz, 2.4GHz and 5.8GHz) ? Are there limitation on the spacing between each turns? Any valuable advise! | 2008/8/27 05:49 |
| 3 | wyslnhhh56 | Hi Rayengine, I know that helical antenna was simulated by CST MWS. In fact there is an example about that antenna in the installation CD. The conformal FDTD or FIT allows to simulate this kind of model. Regards. |

| 4 | pdang | Hi Rayengine, I\E3\D also has a helical antenna as an example. The difficulty with many simulators is that they cannot manage curved structures. But curves and curved surfaces can be approximated with staight segments and pieces of planes. In the case of that example, the approximation is constructed with 12 segments per turn. C\S\T claims to simulate very accurately curved structures without those approximations, but I have not experience with it. Regards Z |

| 6 | scuzt | Reyengine, here you simple helix antenna calculator on: http://www.csgnetwork.com/antennahtcalc.html |

| 7 | btcdtc | XFDTD also has an example project for helix antenna. | 2008/8/27 05:49 |
| 8 | zunwang | you may like to use empire from umist. | 2008/8/27 05:49 |
| 9 | knoxville | hfss can solve it. | 2008/8/27 05:49 |
| 10 | z4120356 | I agree, I use H/F/S/S for this problem. However, drawing the geometry is pretty difficult but the results are good. | 2008/8/27 05:49 |
