[0033] In this example, refer to figure 1 , the dual-band antenna containing a periodic leaky wave structure 5 includes a dielectric plate 1 , a radiator 2 , a matching section 3 , a periodic leaky wave structure 5 , a floor 4 and a feed structure 6 . Wherein, the dielectric plate 1 is composed of a first dielectric layer 101 , a second dielectric layer 102 and a third dielectric layer 103 stacked in sequence. The side where the radiator 2 is disposed on the first dielectric layer 101 , specifically, the side where the radiator 2 is located is the side away from the second dielectric layer 102 . The matching section 3 and the radiator 2 are disposed on the same surface of the first dielectric layer 101 , and the matching section 3 is electrically connected to the radiator 2 .
[0034] In this example, refer to figure 2 , the periodic leaky wave structure 5 includes a first part 501 and a second part 502, specifically, the first part 501 includes at least one first period un...
