Integrated structural-electromagnetic design is one of the current research hotspots in the area of antenna design. In this letter, a mesh refinement method of structure finite elements is developed to produce electromagnetic grids by constructing a quadratic surface over each element. To begin with, the normal vector at each grid node is constructed through the linear combination of normal vectors...
On the inefficient panel adjustment of large reflector antenna, a method for determination of panel adjustment magnitude according to far field pattern is presented. Using the method of Physical Optics (PO), the relationship between the far field value and the node displacement is derived. Then the panel adjustment vector is related to far field pattern with linear equations. Singular value decomposition...
