Detailed Description
The present application will now be described with reference to the accompanying drawings.
As shown in fig. 1 and 5, fig. 1 and 5 show two reflective array antennas provided in different embodiments, in which the reflective array antennas provided in the two embodiments each include the following structures: the feed source array 10, the auxiliary reflecting surface 30 and the main reflecting array 20; in the case of a specific setting, it is,
the sub-reflecting surface 30 is provided on one side of the feed array 10, and the main reflecting array 20 is provided on the other side of the feed array 10 opposite to the sub-reflecting surface 30, wherein,
the feed source array 10 can emit electromagnetic waves in a first polarization direction;
the sub-reflecting surface 30 is used for reflecting the electromagnetic wave with the first polarization direction emitted by the feed source array 10, and allowing the electromagnetic wave with the second polarization direction to pass through, and the first polarization direction and the second polarization direction are perpendicular to each other;
the main reflection array 20 is used for converting the electromagnetic wave with the first polarization direction reflected by the sub reflection surface 30 into the electromagnetic wave with the second polarization direction, and reflecting the electromagnetic wave out.
The feed array 10 includes feed antenna units 11 arranged in an array, and a regulating unit connected to each feed antenna unit 11. Each feed antenna element 11 may be an independent antenna element 11, or may be a sub-array antenna, and the electromagnetic wave in the first polarization direction may be emitted through the feed antenna element 11. The feed antenna unit 11 and the adjusting unit comprise a phase shifting device connected with each feed antenna unit 11 for adjusting phase, and optionally a gain adjusting device connected with each feed antenna unit 11 for adjusting amplitude. The beam direction of the array feed source can be adjusted by adjusting a phase shifting device and/or a gain adjusting device connected with each feed source antenna unit in the array feed source.
After the electromagnetic wave of the first polarization direction is emitted by the feed source array 10, the electromagnetic wave propagates to the sub-reflecting surface 30, and since the sub-reflecting surface 30 has a function of reflecting the electromagnetic wave of the first polarization direction and allowing the electromagnetic wave of the second polarization direction to pass through, the electromagnetic wave emitted by the feed source array 10 to the sub-reflecting surface 30 is reflected to the main reflecting array 20 and reflected again, and at the time of reflection, the main reflecting array 20 can change the polarization direction of the electromagnetic wave, so that the electromagnetic wave reflected again by the main reflecting array 20 becomes the electromagnetic wave of the second polarization direction, and the electromagnetic wave of the second polarization direction can pass through the sub-reflecting surface 30. Therefore, when the sub-reflecting surface 30 is arranged, a structure with a larger area can be arranged, so that the sub-reflecting surface 30 can be ensured to reflect the electromagnetic wave emitted by the feed source array 10 to the main reflecting array 20, and the arranged sub-reflecting surface 30 can not block the emission of the electromagnetic wave of the main reflecting array 20, thereby realizing a beam scanning range which can meet the requirement in a relatively low cost manner, and meeting the requirement of application on a directional diagram.
Referring to fig. 3 and 4, fig. 3 shows a structure of one reflection unit of the main reflection array 20 provided in the present embodiment, and fig. 4 shows a schematic diagram of reflection of electromagnetic waves by the reflection unit. Referring to fig. 1, the main reflective array 20 of the present embodiment includes a plurality of reflective units arranged in an array. In a specific arrangement, as shown in fig. 1, a plurality of reflection units are arranged in a rectangular array; when the reflection unit includes the substrate 21 and the reflection patches 22 as shown in fig. 3, the reflection patches 22 are provided on the substrate 21, and when the reflection units are provided in an array, the substrates 21 of the plurality of reflection units are integrated. That is, the entire primary reflective array 20 comprises a monolithic substrate 21 and reflective patches 22 affixed to the substrate 21 and arranged in an array. In the above structure, of the main reflection array 20The function is mainly achieved by the reflective patch 22, that is, the polarization direction of the electromagnetic wave is changed by the reflective patch 22, and the reflective patch 22 is the reflective patch 22 that rotates the polarization direction of the incident electromagnetic wave by 90 degrees. Specifically, as shown in fig. 4, the polarization direction of the electromagnetic wave emitted from the feed source array is 45 degrees different from the polarization direction of the reflective patch 22, and by designing the size of the reflective patch 22, when the electromagnetic wave is reflected on the reflective patch 22, the delay of the component parallel to the polarization direction of the reflective patch 22 is 180 degrees different from the delay of the component perpendicular to the polarization direction of the reflective patch 22, so that when the electromagnetic wave irradiates the main reflective array 20, the polarization direction of the electromagnetic wave is changed from the first polarization direction
Is converted into the second polarization direction
The polarization direction of the incident electromagnetic wave is rotated by 90 degrees. So that the reflected signal can be transmitted through the secondary reflective array.
In a specific arrangement, the sub-reflecting surface 30 may be arranged in different ways. The detailed description is as follows.
Example 1
As shown in fig. 1 and fig. 2, fig. 1 shows a structure of the reflective array antenna, and fig. 2 shows a schematic structural diagram of the sub-reflecting surface 30. As can be seen from fig. 1, in the reflective array antenna provided in this embodiment, the central points of the sub-reflective surface 30, the main reflective array 20, and the feed array 10 are located on the same straight line, and the three are arranged in parallel.
As shown in fig. 2, in the present embodiment, the sub-reflecting surface 30 is a plate-shaped structure 31, specifically, different shapes such as a rectangle, a circle, an ellipse, etc., a plurality of single-polarized slots 312 are arranged in an array on the plate-shaped structure 31, and a polarization direction of the single-polarized slots is perpendicular to a polarization direction of the electromagnetic wave emitted from the feed source array 10, specifically, the sub-reflecting surface 30 includes a substrate 311, the substrate 311 is rectangular, and a plurality of single-polarized slots 312 are arranged in an array on the substrate 311, taking a placement direction of the antenna shown in fig. 1 as a reference direction, in the present embodiment, a length direction of the slots 312 is a vertical direction, and each slot 312 allows the electromagnetic wave in the second polarization direction to pass through. That is, the polarization direction of the slot 312 is perpendicular to the polarization direction of the signal (the electromagnetic wave emitted by the feed source array 10), so that the signal emitted by the feed source is reflected on the sub-reflective array (but the signal with the same polarization direction as the slot 312 can penetrate the sub-reflective array); the array is a non-uniform array, different delays of signals on each unit are realized by designing different shapes of the gaps 312 so as to control phases, so that reflected signals in the scanning process of a feed source wave beam (feed source array 10) can always fall in the range of a main reflection array, namely, electromagnetic waves in a first polarization direction emitted by a feed source can be reflected to the main reflection array 20 for reflection.
Specifically, there are many ways to design different shapes of the slot 312 to achieve different delays of the signal on each unit, and the width, shape, etc. of the slot are used, which is not limited herein. In the placement mode of the present embodiment, the phase delay of the slit gradually decreases in the arrangement direction from the center to the edge of the sub-reflecting surface. The phase delay of the slit near the center of the sub-reflecting surface is larger, the phase delay of the slit near the edge is smaller, and the phase delay of the slit from the center to the edge is gradually reduced. The purpose of the design is to compensate the propagation path difference between the position of the sub-reflecting surface unit and the main reflecting surface through the phase delay difference, so that the signals reflected by the gaps on the sub-reflecting surface can just fall in the range of the main reflecting array after space synthesis, and the energy cannot be wasted.
Example 2
As shown in fig. 5 and fig. 6, fig. 5 is a reflective array antenna according to another embodiment of the present application, and fig. 6 is a schematic structural diagram of a sub-reflecting surface 30 according to the present embodiment.
As shown in fig. 5, the center points of the feed source array 10, the main reflection array 20, and the sub-reflection surface 30 provided in this embodiment are located on the same straight line, and the three are arranged in parallel, in this embodiment, since the sub-reflection surface 30 has an arc structure, the parallel of the sub-reflection surface 30 and the main reflection array 20 means that the plane where the edge of one surface of the sub-reflection surface 30 facing the main reflection array 20 is located is parallel to the main reflection array 20.
Referring to fig. 5 and 6 together, as can be seen from fig. 5 and 6, the sub-reflecting surface 30 provided in this embodiment is a polarization grid 321, the placement direction of the antenna shown in fig. 5 is taken as a reference direction, the length direction of the polarization grid 321 is taken as a vertical direction, and the polarization direction of the polarization grid 321 is perpendicular to the polarization direction of the signal transmitted by the feed source array 10. Therefore, the signal emitted from the feed source is reflected on the secondary reflective array (but the signal with the same polarization direction as the slit 312 can penetrate the secondary reflective array); the sub-reflecting surface 30 is an inwardly concave arc plate 32, and one surface of the arc plate 32 facing the feed source array 10 is inwardly concave. In a specific embodiment, the sub-reflecting surface 30 is in a parabolic shape, and the design is to compensate a propagation path difference between each reflecting point position of the sub-reflecting surface and the main reflecting surface through a cambered surface structure, so that signals reflected by the slits on the sub-reflecting surface can be exactly within the range of the main reflecting array after being spatially synthesized, and thus, after a feed beam (electromagnetic waves emitted by the feed array 10) is reflected by the polarization grid 321, the signals can cover the main reflecting array 20.
An embodiment of the present application further provides a communication device, which includes any one of the reflective array antennas described above.
In the above-mentioned embodiment, the antenna composed of the feed array 10, the main reflection array 20, and the sub-reflection surface 30 is adopted, and after the feed array 10 emits the electromagnetic wave of the first polarization direction, the electromagnetic wave propagates to the sub-reflection surface 30, since the sub-reflection surface 30 has a function of reflecting the electromagnetic wave of the first polarization direction and allowing the electromagnetic wave of the second polarization direction to pass through, the electromagnetic wave emitted from the feed array 10 to the sub-reflection surface 30 is reflected to the main reflection array 20 and reflected again, and at the time of reflection, the main reflection array 20 can change the polarization direction of the electromagnetic wave, so that the electromagnetic wave reflected again by the main reflection array 20 becomes the electromagnetic wave of the second polarization direction, and the electromagnetic wave of the second polarization direction can pass through the sub-reflection surface 30. Therefore, when the sub-reflecting surface 30 is arranged, a structure with a larger area can be arranged, so that the sub-reflecting surface 30 can be ensured to reflect the electromagnetic wave emitted by the feed source array 10 to the main reflecting array 20, and the arranged sub-reflecting surface 30 can not block the emission of the electromagnetic wave of the main reflecting array 20, thereby realizing a beam scanning range which can meet the requirement in a relatively low cost manner, and meeting the requirement of application on a directional diagram.
