Abstract This letter proposes a measurement technique for the relative phase of a 5G new radio (NR) signal. The total radiated power (TRP) is measured to evaluate wireless equipment. However, this cannot be implemented using the near‐field measurem

In this paper, we propose a compact-standard antenna method (C-SAM) for antenna calibration above 1 GHz. The test-site evaluation of the fully-anechoic room (FAR) condition satisfied the free-space conditions. When the C-SAM was compared with convent

The dynamic responses of a tethered satellite system after debris release were analyzed. The tethered satellite system is modelled as two point masses connected by a string. The equations of motion for the tethered satellite system are derived by usi

Herein we analyze the dynamic behavior of a tethered satellite system for space debris capture, considering the large deformation of a tether. The tethered satellite system is modeled as two point masses and a string, and the equations of motion of t
