Embodiment Construction
[0023] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.
[0024] According to an embodiment of the present invention, a miniaturized antenna unit with a controlled beam width is provided, figure 2 It is a structural diagram of the miniaturized antenna unit, including: a radiation sheet 10 , a dielectric layer 20 , a microstrip slot antenna substrate 30 and a reflection cavity 40 .
[0025] Among them, such as figure 2 As shown, the dielectric layer 20 is arranged between the radiation sheet 10 and the front of the microstrip slot antenna substrate 30, and the dielectric constant of the dielectric layer 20 is greater than that of air; the microstrip slot antenna substrate 30 adopts a high dielectric constant substrate sheet 301, and the dielectric constant of the high diele...
