In this study, a millimeter-wave far-field range antenna measurement system is proposed for W-band monopulse antenna measurements. Since the W-band monopulse antenna installed in radar systems has many input/output ports, multiple calculations are re

A compact method for extracting the parameters of the effective roughness model is introduced, which predicts statistical field scattering from rough surfaces. The proposed method includes quasi-plane wave generation using a parabolic reflector, samp

This paper proposes a field probe to measure the power density (PD) at a millimeter-wave (mmWave) frequency band. The proposed probe is composed of a loop antenna in which one end is terminated with a load resistor. Such a structure enables the simul
