Specifically, in the embodiments of the present invention, the microwave detection module with an extended beam angle includes at least three dual-coupled poles 10 and an electromagnetic reflection surface 20, wherein each of the dual-coupled poles 10 is located at a space corresponding to the electromagnetic reflection surface 20 and at a space spaced from the electromagnetic reflection surface 20, wherein the electromagnetic reflection surface 20 is formed on the surface of the conductive plate, so as to form a directional radiation characteristic of the microwave detection module with an extended beam angle in the target detection direction by the reflection characteristic of the electromagnetic reflection surface 20 on the electromagnetic wave, that is, the target detection direction is the direction from the electromagnetic reflection surface 20 to the dual-coupled poles 10, so that the microwave detection module with an extended beam angle can form a directional radiation space 100 suitable for detecting the object movement in the directional space, and is favorable for avoiding the microwave detection module with an extended beam angle from self-exciting to improve the interference resistance of the microwave detection module with an extended beam angle The performance of the interference.

Further, each of the dual-coupled dipoles 10 includes two radiation sources 11, wherein each of the radiation sources 11 is disposed around a target direction axis (corresponding to Z axis in the figure) pointed by the target detection direction, wherein the radiation sources 11 are divided into a first radiation source 111 and a second radiation source 112 according to the polarity of the radiation sources 11 in the corresponding feeding design, wherein the first radiation source 111 has a first feeding end 1111 and is disposed as a conductor extending from the first feeding end 1111Wherein the second radiation source 112 has a second feeding end 1121 and is configured as a conductor extending with the second feeding end 1121 as an end, wherein the first radiation source 111 and the second radiation source 112 respectively extend in a direction away from each other with the first feeding end 1111 and the second feeding end 1121 as ends and respectively have a line length greater than or equal to λ/16, wherein the vector is counted with the first feeding end 1111 as a starting point and the second feeding end 1121 as an end point in the same dual-coupled pole 10

Where | a | ≦ λ/32, that is, the first feeding end 1111 and the second feeding end 1121 of the same dual-coupling pole 10 are close to each other within a distance range of λ/32 or less, where λ is a wavelength parameter corresponding to a feeding frequency, so that on the premise that the dual-coupling poles 10 satisfy corresponding impedance matching, when each of the dual-coupling poles 10 is fed at the first feeding end 1111 and the second feeding end 1121, respectively, an electric field coupling sufficient for radiating electromagnetic waves outwards can be generated between the first radiation source 111 and the second radiation source 112 of each of the dual-coupling poles 10 to form the radiation space 100.

Preferably, the distance between the first feeding end 1111 and the second feeding end 1121 of the same dual-coupling pole 10 tends to be λ/128 within a tolerance of 10%, i.e. 0.9 λ/128 ≦ a ≦ 1.1 λ/128, so as to reduce the loss of mutual coupling between the first radiation source 111 and the second radiation source 112 when the electric field coupling is generated between the first radiation source 111 and the second radiation source 112 of each of the dual-coupling poles 10.

On the basis of the above structure, the phase difference between the dual-coupled poles 10 depends on the phase point of the first feeding end 1111 and the second feeding end 1121 and the vector

Wherein the dual-coupled pole 10 is at the first feed end 1111 and theThe phase point of the second feeding end 1121 depends on the feeding design of the dual-coupled pole 10, including the feeding circuit design and the feeding source design, wherein the vector quantity

Specifically, referring to fig. 3A and 3B of the drawings of the present invention, the structure and radiation pattern of the microwave detection module with an expanded beam angle according to an embodiment of the present invention are illustrated, respectively, in which each of the first radiation source electrodes 111 is arranged radially around the target direction axis in a radial direction of the target direction axis in a state where the first feeding end 1111 is close to the target direction axis, and each of the second radiation source electrodes 112 is arranged radially around the target direction axis in a radial direction of the target direction axis in a state where the second feeding end 1121 is close to the target direction axis, so as to facilitate the collective feeding of each of the first feeding ends 1111 and the collective feeding of each of the second feeding ends 1121 such that each of the dual-coupled poles 10 can be fed with a feeding circuit design using feeding with the same phase and the same phase, and the feed circuit design and the feed source design of the microwave detection module for expanding the beam angle are simplified.

It will be appreciated that each of the dual-coupled poles 1 is designed to operate with a feed circuit fed in phase with the same feed sourceThe phase difference between the opposite pair of dipole coupling poles 10 and the corresponding two vectors when 0 is fed

The included angles are corresponding. That is, in this embodiment of the present invention, when each of the dual-coupled poles 10 is fed with a feed circuit design using in-phase feeding with the same feed source, the physical arrangement of each of the dual-coupled poles 10 is such that two of the vectors of at least one pair of the dual-coupled poles 10 opposite to each other are arranged

With an included angle of greater than 90 degrees therebetween. On the basis of a feeding design that each of the dual-coupling poles 10 is fed at the same phase point, the dual-coupling poles 10 are physically arranged such that an electric field direction angle difference of more than 90 degrees is formed between electric fields of at least one pair of the dual-coupling poles 10 that are opposite to each other, and a phase difference of more than 90 degrees is formed between at least one pair of the dual-coupling poles 10 that are opposite to each other, so that the radiation space 100 is stretched in two corresponding opposite radial directions of the target direction axis.

Having an angle greater than 90 degrees therebetween, thereby forming the radiation space 100 stretched in each radial direction of the target direction axis, increasing a plane beam angle of the radiation space 100 corresponding to each radial direction of the target direction axis.

It is worth mentioning that the same feed source is usedWhen each of the dual-coupling poles 10 is fed by the same-phase feeding circuit design, based on the structural relationship that the first feeding end 1111 and the second feeding end 1121 of the same dual-coupling pole 10 are close to each other within a distance range of λ/32 or less, in this embodiment of the present invention, the adjacent first radiation source 111 and the second radiation source 112 are allowed to be divided into the same dual-coupling pole 10, and the opposite first radiation source 111 and the second radiation source 112 are also allowed to be divided into the same dual-coupling pole 10. That is, the first radiation source 111 can generate electric field coupling with the adjacent second radiation source 112 and the opposite second radiation source 112 at the same time. Therefore, on the basis of the structure that each of the dual-coupling poles 10 includes two radiation sources 11, the determination of the phase difference between the opposing dual-coupling poles 10 should consider all the division ways of the dual-coupling poles 10, that is, the determination of the two vector quantities of at least one pair of the opposing dual-coupling poles 10 according to one of the division ways of the dual-coupling poles 10
