Embodiment Construction
[0037] Embodiment of Dual Polarized Antenna Suitable for Wireless Local Area Network
[0038] This example Figures 1 to 3 As shown, this embodiment of a dual-polarized antenna applicable to a wireless local area network includes a first-layer dielectric board 1 , a second-layer dielectric board 5 and a grounding board 4 . In this example, the first layer of dielectric board 1, the second layer of dielectric board 5 and the grounding board 4 are the same square whose side length is L=51mm, the first layer of dielectric board 1 is the uppermost layer, and the second layer of dielectric board is below it 5. The grounding plate 4 is on the bottom layer, and the four sides of the three-layer board are overlapped and stacked, and each layer is attached to each other.
[0039] The first layer of dielectric plate 1 in this example is the dielectric constant ε r is 4.4, tangent loss angle tanσ is 0.02, and a single-sided copper clad laminate with a thickness of 2 mm, the metal radia...
