Example Embodiment
[0036] Example 1:
[0037] Such as figure 1 with figure 2 As shown, this embodiment provides a high-gain slot array antenna. The slot array antenna is a substrate integrated waveguide (SIW) slot array antenna and can be applied to a mobile communication device. It includes a dielectric substrate 1, a patch 2, The microstrip feeder 3 and several first through holes 4, the patch 2 and the microstrip feeder 3 are arranged on the upper surface (front) of the dielectric substrate 1, and the lower surface (back) of the dielectric substrate 1 is the floor 5, that is, the floor 5 covers The entire lower surface of the dielectric substrate 1.
[0038] The cross-sectional shape of the dielectric substrate 1 is rectangular, with a thickness of 0.8 mm, a dielectric constant of 2.55, and a dielectric loss angle of 0.0029. Since there is only one layer of the dielectric substrate 1, it is easy to integrate in a plane, simple and inexpensive, and has good performance.
[0039] Seen from the upper...
Example Embodiment
[0050] Example 2:
[0051] The main feature of this embodiment is that the thickness of the dielectric substrate 1 is 0.6 mm. The rest is the same as in Example 1.
Example Embodiment
[0052] Example 3:
[0053] The main feature of this embodiment is that the thickness of the dielectric substrate 1 is 1 mm. The rest is the same as in Example 1.
[0054] To sum up, the dielectric substrate of the slot array antenna of the present invention is provided with patches, and six radiation slots are opened on the patch. The six radiation slots form a six-slot array, which is compared with a double-slot or four-slot array antenna. Higher gain, without having to use multiple antenna elements to form an array to achieve the same gain effect, thus simplifying the array structure, and due to the use of a dielectric substrate, easy planar integration, simple and cheap technology, and good performance; in addition, the The invented slot array antenna divides the six radiation slots into two rows, and the radiation slots in both rows are three. The radiation slots on both sides of each row of radiation slots are loaded with eight through holes, which can suppress the interferen...
