Abstract

This paper presents gain measurement results of a printed patch antenna in a probe station environment at millimeter wavelengths. The one-antenna gain measurement method relying on the use of a reflective plate and measurement of the reflection coefficient is applied. The accuracy of the measurement is improved by moving the reflective plate and thus changing its distance from the antenna. In addition, the time-gating is used in order to avoid the effect of the multiple reflections and other stray signals from near-by reflecting objects. The size requirement for the reflective plate is experimentally studied by using three different plate sizes. Also, different reflective plate distance ranges for the gain retrieval are investigated. The obtained results suggest that the distance range of 20-30 mm and reflective plate width of 30 mm are sufficient to provide accurate gain results for a patch antenna at W-band.
