Abstract EN
An approximation mathematical formula to compute the distorted radiation pattern for reflector antennas is presented.
In this approximation formula, besides the phase error caused by the structural deformation being added in the far field integral, the surface normal vector variation is also taken into consideration.
The formula is derived by expanding the surface normal vector into a first-order Taylor series and the phase error into a second-order Taylor series.
By assembling the integrals including the contributions of both surface normal vector variation and phase error, the far field electrical vector expressed as a function of structural nodal displacements is further obtained in a matrix form.
Simulation results of a distorted reflector show the application of this formula.
