Embodiment 1
[0046] In Embodiment 1, the first plate surface is the upper surface of the dielectric substrate, and the second plate surface is the lower surface of the dielectric substrate.
[0047] like figure 1 As shown, a three-frequency common-aperture fusion antenna includes a low-frequency unit 1, a non-uniform surface 2, an intermediate frequency unit 3, a high-frequency unit 4, and a reflector 5 from top to bottom. The working frequency band of the low-frequency unit is 690- 960MHz, the working frequency band of the intermediate frequency unit is 1700MHz-2200MHz, and the working frequency band of the high frequency unit is 4800MHz-5000MHz.
[0048] The high-frequency unit 4 is located above the reflector 5, and the distance between the two is 19 mm in this embodiment. The intermediate frequency unit is located above the high frequency unit. In this embodiment, the distance between the two is 17mm. The low frequency unit is located above the intermediate frequency unit. In this emb...
