Design of a Microwave Power Detection System in the 5G-Communication Frequency Band

Abstract

At present, the proposed microwave power detection systems cannot provide a high dynamic detection range and measurement sensitivity at the same time. Additionally, the frequency band of these detection systems cannot cover the 5G-communication frequency band. In this work, a novel microwave power detection system is proposed to measure the power of the 5G-communication frequency band. The detection system is composed of a signal receiving module, a power detection module and a data processing module. Experiments show that the detection frequency band of this system ranges from 1.4 GHz to 5.3 GHz, the dynamic measurement range is 70 dB, the minimum detection power is −68 dBm, and the sensitivity is 22.3 mV/dBm. Compared with other detection systems, the performance of this detection system in the 5G-communication frequency band is significantly improved. Therefore, this microwave power detection system has certain reference significance and application value in the microwave signal detection of 5G communication systems.

Ultra-thin water-based metasurface with dual-broadband perfect absorption

“…Metasurfaces are proving to be of significant value in applications such as radar stealth [20], electromagnetic compatibility [21], electromagnetic interference [22]. Furthermore, with the accelerated development of 5G high-frequency communication technology [23], there has been an increase in electromagnetic pollution phenomenon and, consequently, a growing need for electromagnetic shielding devices. The broadband metasurface absorber has emerged as an effective solution to address this issue.…”
