A new proposal to convertnear-field into far-field for parabolic reflectors

A modeling of a 1.5-m diameter parabolic reflector using the discrete Pocklington equation working at a frequency of 2.45 GHz has been presented; the proposal allows to obtain far-field radiation pattern from the reflected field close to the surface plate which has been first modeled in CST MWS and then it was converted into a current vector using the discrete Pocklington equation. Finally, the far-field pattern using antennas array theory was obtained. To validate the results, they compared them with the measurements of a real parabolic reflector.
