2COMU is glad to announce a new future in GEMS software to generate a conformal patch array or FSS array on an arbitry curved surface. If the curved surface can be expressed as an analytic formula, GEMS can directly generate the curved surface with or without thickness through an analytic expression. The conformal patch array can be generated using the analytic formula and the edge lengthes remain same in the curved and flat shape. If the curved surface is imported from a CAD file and may not be expressed as an analytic formula, GEMS can calculate the positions of the patches on the curved surface, and the users can palce an arbitry shape of patch on to the curved surface without leaving the GEMS interface.
New futures in GEMS software

We can generate a parabolic structure through an analytic formula (z=-z-sqrt(x^2+y^2)/(4f)) based on a thin cylinder. This parabolic structure can be used as the antenna radome. GEMS allows the user to pick up and deplicate a surface. Select this surface and specify the positions of the patch elements on this surface, and specify the unit size. |
We can import a practical model into GEMS interface via some typical CAD file formats such as SAT, ProE, IGES, etc.. We can pick up a curved surface from the complex model and then generate the dielectric coating and patch array on the curved surface. After we complete the model modifications and then place the modfied model back to the original model. |

Draw an element pattern inside a unit, which center must be located at the orgin point. In order to generate a conformal patch, we need to specify a thickness. when we carry out the operation between the curved surface and elements, the conformal patch can be generated. |
Pick up a piece from the car model, and create a new project for the small piece. Select the surfce and duplicate a new surface, and then create a thickness for the duplicated surface (dielectric coating). Select the top surface of the dielectric coating, and deplicate a new surface, namely, patch layer. |

| Combine the position information of the patch on the curved surface and the unit structure to generate the patch array on the curved surface. Use the curved surface to subtrct the patch array to get the slot array on the curved surface. |

| Select the surface of the antenna radome and duplicate one more curved surface. Use this curved surface to subtract the slot array, we can get the conformal patch array that fit to the curved surface exactly. |
