Description of the Invention: [Technical Field] [0001] The present invention relates to an electromagnetic radiation detecting device [0002] [0003] [0004] [0005] 099136102 [Prior Art] Electromagnetic compatibility according to various countries ( The Electro-Magnetic C〇mpatibil_ ity 'EMC' directive requires electronic products to be subjected to Electromagneti (EMI) testing before entering the country's market. Only products that meet the country's EMC standards can be sold in the country. Therefore, it is especially important to find out the electromagnetic source of the clock accurately in the development stage of the electronic product. I [Abstract] In view of the above, it is necessary to provide a source of electromagnetic radiation. Magnetic spokes, an electromagnetic radiation detecting device, a bar, a stalk, a net, a sling, a rod antenna, and an electromagnetic radiation measuring device, the absorbing antenna includes a body and a suspension with the antenna, the transfer: a part turn The electromagnetic radiation detecting member includes a fixing portion, a connecting wire and a detecting probe, and the top surface of the fixing portion has a fitting portion electrically connected to the connecting portion. The connecting wire ^ is connected to the detecting probe at the other end of the connecting wire. Compared with the prior art, the electromagnetic radiation touches the test point of the electronic device to be tested, and the high frequency current emitted by the probe pin receives the electromagnetic wave from the probe body to the outward direction, thereby making the antenna body form No. A_ The coin cone logarithmic period hybrid antenna c Interference 0992063120-0 201217819 and the spectrum analyzer can easily find the electromagnetic radiation source which is mainly exceeded by receiving the electromagnetic wave radiated from the antenna body. The operation is very convenient. [0007] [0007] [0008] [0009] Referring to FIG. 1, a preferred embodiment of the electromagnetic radiation detecting apparatus 1 of the present invention includes a whip antenna 10 and an electromagnetic radiation detecting member. The 〇 line 1 〇 includes an antenna body 12 and an adapter 14 connected to the antenna body , 2, the antenna body 12 can be arbitrarily rotated around the top of the adapter 14 , and the bottom of the 玄 adapter 14 is further A stud 142 is electrically connected to the antenna body 12. In other embodiments, the whip antenna 1〇 may also be a whip antenna of other configurations: since it is a conventional technology: Therefore, the electromagnetic radiation detecting member 2 includes a fixing portion 22 and a connection. Wire 24 and probe probe 26. In the present embodiment, the fixing portion 22 is a truncated cone body, and other embodiments may be designed in other shapes such as a rectangular parallelepiped or the like. The top surface of the fixing portion 22 is provided with a screw hole 222, and the screw 142 on the rod antenna 1 can be screwed into the screw hole 222. One end of the connecting wire 24 is electrically connected to the screw hole 22 2 inside the fixing portion 22 (not shown in the drawing).

Sexual connection. Application of the whip antenna 10 to detect the form of an electronic device (such as a computer motherboard) 'Edit 0101 Page 4 / 9 pages 0992063120-0 [0009] 201217819 Before electromagnetic interference 'Firstly, according to the test requirements, the frequency point to be tested is obtained. (This is a conventional technique 'not detailed here, and then according to the frequency and wavelength conversion formula (again = C / V, λ is the wavelength, (: is the speed of light, ν is the frequency) to obtain the wavelength λ of the test. The whip antenna 1 〇 will resonate with the high-frequency current received by the detecting probe 26 during operation, and the length L of the antenna body 12 of the whip antenna 10 when resonating is one quarter of the wavelength corresponding to the resonant frequency, It can be obtained that the length of the antenna body 12 is l=1/4A. [0010] ο In the specific test, a pair of cone-log-period hybrid antennas and a spectrum analyzer connected to the double-cone log-period hybrid antenna are also needed. Tested, because the double-cone logarithmic period hybrid antenna and spectrum analyzer are common instruments in the field of testing electromagnetic interference, so here is no specific description 〇丨|_¥丨义丨录[0011] Frequency point The fixing portion 22 of the electromagnetic radiation detecting device 100 is placed in the vicinity of the electronic device to be tested, and then the length of the antenna body 12 of the whip antenna 10 is adjusted to be a quarter of the wavelength corresponding to the brightness point to be tested. The direction of the antenna body 12 of the whip antenna 10 is adjusted to be consistent with the direction of the double-cone logarithmic hybrid antenna. After the adjustment is completed, the probe probe 26 is contacted with the test point of the electronic device to be tested that has been turned on (eg, On the wafer pin), the antenna body 12 of the whip antenna 10 receives the high frequency current emitted by the probe probe 26 and causes the antenna to vibrate. Then the antenna body 12 radiates corresponding electromagnetic waves outward. The double cone logarithmic period The hybrid antenna receives the electromagnetic wave k number ' radiated by the antenna body 12 and displays a change of the corresponding frequency band waveform on the spectrum analyzer, since the length of the antenna body 12 has been adjusted to a quarter of the wavelength corresponding to the frequency point to be tested. And its direction is also adjusted to the double cone pair 099136102 Form No. A0101 Page 5 / Total 9 Page 0992063120-0 201217819 The alignment is uniform, so that the antenna body 12 can obtain a better emission effect, so that the difference in radiation intensity of different test points in the waveform on the spectrum analyzer is more obvious, thereby making it easier to find the electromagnetic Φδ source which is mainly exceeding the standard.
