A design of low-power portable broadband radio frequency signal detection pen

Abstract： This paper, prioritizing portability and low power consumption, innovatively proposes a pen-shaped portable RF signal detection pen for the first time. It aims to address the challenges of inspecting and repairing communication equipment in extreme environments such as high-cold, high-altitude, high-temperature, or high-latitude regions, where carrying conventional laboratory equipment is inconvenient, hazardous, and difficult to power. The proposed detection pen not only significantly reduces the burden of carrying complex detection instruments in harsh environments but also allows for the conservation of space and energy for carrying other essential items. Experimental tests demonstrate that the detection pen can effectively detect RF signals within the frequency range of 1~23 GHz and power range of -45 dBm to +3 dBm. The experimental results are consistent with the theoretical design, thereby validating the feasibility and efficiency of the proposed method.
