EIRP estimation using a phase-less spherical near field measurement

Abstract

This paper presents a far field estimation method using a phase-less spherical near field data, which overcomes OTA test problems such as measurement cost and time. The method is based on matrix equation of radiation from wire grid model by introducing three techniques such as a wire grid source model, an adjustment of matrix equation, and the optimal sampling method. We confirm that far field estimation is conducted with high accuracy by introducing three new techniques in simulation.
