Problems solved by technology
At the same time, the thermoelectric element is used as the sensitive element, the measurement sensitivity is low, and the response time is long, so it can only be used for the leakage measurement of the continuous wave source
There are a small number of probes in foreign countries that use three-dimensional structures, but so far no completely concentric and orthogonal three-dimensional probes have been seen. This type of probe still needs to be rotated during measurement, so it can only measure the leakage of continuous wave sources

Embodiment Construction
[0030] The composition of the antenna array is to open a rectangular groove 13 at the base circle center of the semicircle thin plate 14, insert the base of the triangular thin plate 7 in the base groove 13 of the semicircle thin plate 14, make the two thin plates perpendicular to each other, and the bottom edge Centers 8 and 12 coincide, and three mutually perpendicular rectangular copper strips are respectively etched on the semicircular thin plate 14 and the triangular thin plate 7, and the distribution positions are as follows: figure 2 , 3 As shown; thus forming three pairs of concentric and mutually perpendicular dipoles (two rectangular copper strips whose spatial positions are on a straight line form a pair of dipoles). Weld Schottky diodes and signal leads at the center of each pair of dipoles, and pay attention to keep the insulation between the three dipoles and signal lines, such as Figure 4 shown.
[0031] Such as Figure 5 As shown, put the prepared antenna ...

The invention provides a high-sensitivity, isotropic space electromagnetic wave leakage detection head, which consists of three mutually perpendicular concentric dipoles and three high-sensitivity detection diodes to form an antenna array. The entire antenna array is enclosed in a probe cover made of polyethylene material, and the three groups of signals are led out with six-core shielded wires. Due to its special structure, this probe has the characteristics of isotropy, and there is no need to rotate the probe when measuring space electromagnetic wave leakage; it can not only detect electromagnetic wave leakage of continuous wave sources, but also solve the problem of leakage measurement of low repetition frequency pulse modulation radiation sources.
Description
Technical field: [0001] The invention belongs to the field of electromagnetic field technology, and in particular relates to electromagnetic wave detection technology. Background technique [0002] Space electromagnetic wave leakage detection takes weak electromagnetic radiation as the test object, and is one of the important research contents in the research directions of environmental monitoring, environmental protection, electromagnetic compatibility and bioelectronic effects. The space electromagnetic wave leakage detection sensor is the core device for this test. At present, space electromagnetic leakage probes mostly adopt a planar two-dimensional structure, such as figure 1 As shown, the monopoles 1 and 2 form a dipole, and the two pins of the detection diode are respectively welded on the monopoles 1 and 2, and the two pairs of dipoles are perpendicular to each other to form a space electromagnetic leakage probe with a planar two-dimensional structure. , the probe n...
