Abstract

The novel differential phase measurement method has been demonstrated at millimeter waves using three power meters instead of a phase-sensitive measurement device.
Compared to conventional antenna phase measurement methods, the differential phase method provides several advantages. This method requires no rotary joints or flexible cables. Phase-locking of the oscillators is not necessary. It is shown that the phase measurement device can be replaced by three power dividers and three power meters or detectors.
The phase patterns measured with three power meters agree well with the measurements carried out using an antenna measurement receiver as well as with the theory
