Description

technical field [0001] The invention relates to a detection device, in particular to a wireless electromagnetic wave detection device. Background technique [0002] In the field of radio wave detection technology, the existing electromagnetic radiation detector usually includes a radio frequency antenna, a high-speed operational amplifier peak detection circuit unit, a common operational amplifier signal amplification circuit unit and a DC output display circuit unit. [0003] Generally, for ultra-wideband radio frequency antennas, the relative area of ​​the antenna is required to be relatively large, in order to achieve a relatively flat input impedance change with the increase of frequency, that is, the bandwidth of the antenna is relatively wide. But a larger antenna will reduce the impedance and make the input signal low, which makes the detection inconvenient. The antenna settings of some radio wave radiation detectors obviously cannot achieve the required broadband eff...
