specific Embodiment approach 1

[0007] Specific implementation mode one: combine Figure 1 to Figure 4 Describe this embodiment mode, a slot array antenna based on a dielectric integrated ridge waveguide described in this embodiment mode includes a bottom metal layer 1, a first dielectric plate 2, a first ridge metal layer 3, a second ridge metal layer 4, a second dielectric The plate 5 and the seam metal layer 6, the first dielectric plate 2 and the second dielectric plate 5 are rectangular plates, the first ridge metal layer 3 is a rectangular metal sheet, the bottom metal layer 1, the first dielectric plate 2, the first ridge metal Layer 3, the second ridge metal layer 4, the second dielectric plate 5, and the seam metal layer 6 are stacked sequentially from bottom to top, the first ridge metal layer 3 is located in the middle of the first dielectric plate 2, and the first ridge metal layer 3 is along the The center line of the length direction coincides with the center line of the first dielectric board ...

specific Embodiment approach 2

[0008] Specific implementation mode two: combination Figure 1 to Figure 4 To illustrate this embodiment, the length of the bottom metal layer 1 of a slot array antenna based on a dielectric integrated ridge waveguide described in this embodiment is 110 mm, the width of the bottom metal layer 1 is 42 mm, and the thickness of the bottom metal layer 1 is 0.017 mm to 0.017 mm. 0.035mm.

[0009] The technical effect of this embodiment is that the setting of the length and width can reduce the area of ​​the antenna as much as possible to realize the miniaturization of the antenna, and the setting of the thickness of the metal layer can ensure the reduction of resistance loss. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0010] Specific implementation mode three: combination Figure 1 to Figure 4 Describe this embodiment, the length of the first dielectric plate 2 of the slot array antenna based on the dielectric integrated ridge waveguide described in this embodiment is 110 mm, the width of the first dielectric plate 2 is 42 mm, and the thickness of the first dielectric plate 2 is 1.45mm˜1.53mm, and the relative permittivity of the first dielectric plate 2 is 4.4˜4.6.

[0011] The technical effect of this embodiment is: the common FR-4 substrate material is selected for the dielectric plate, and the relative permittivity of this material is relatively large, which facilitates the miniaturization of the antenna; in addition, the selected thickness dimension is also a common FR-4 The size of the 4-type plate is convenient for mass production of the antenna. Other compositions and connections are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to an array antenna, in particular to an aperture array antenna based on medium integration ridge waveguide. The aperture array antenna based on medium integration ridge waveguide solves the problem that an existing aperture antenna array is small in bandwidth, so that the application range is limited. The aperture array antenna based on medium integration ridge waveguide comprises a bottom metal layer, a first medium plate, a first ridge metal layer, a second ridge metal layer, a second medium plate and an aperture metal layer, wherein the bottom metal layer, the first medium plate, the first ridge metal layer, the second ridge metal layer, the second medium plate and the aperture metal layer are arranged sequentially from bottom to top in an overlapped mode. The aperture array antenna based on the medium integration ridge waveguide is applied to the field of wireless communications.

Description

technical field [0001] The invention relates to an array antenna, in particular to a slot array antenna based on a dielectric integrated ridge waveguide. Background technique [0002] Due to the characteristics of low loss, low profile, small size and light weight, substrate integrated waveguide has received extensive attention in recent years. Researchers have developed many slot antenna arrays based on this waveguide. However, the bandwidth of this type of antenna generally does not exceed 5%, which limits its application. Therefore, some researchers have proposed a slot array antenna based on a ridged substrate integrated waveguide, which increases the bandwidth of the antenna to 8.5% (frequency 24.85- 27.05GHz), but the bandwidth is still low. Contents of the invention [0003] In order to solve the problem that the existing slot array antenna has a small bandwidth, which results in a limited application range, the invention further proposes a slot array antenna based...
