IMPLEMENTATION OF EXTRAPOLATION AND PLANAR NEAR-FIELD ANTENNA MEASUREMENT SYSTEM FOR W-BAND ANTENNAS

摘要

Korea Research Institute of Standards and Science (KRISS) has upgraded antenna measurement system to W-band (75 GHz approx 110 GHz). This paper describes the antenna measurement facility that consists of a planar near-field scanner, a microwave subsystem and an extrapolation range, and measurement results. The microwave subsystem is adjusted to meet system power budget. Comparison result of on-axis horn antenna gains from extrapolation method based on three-antenna technique with those from planar near-field measurement shows good agreement within 0.15 dB.
