Embodiment Construction
[0031] Such as Figure 1 to Figure 3 As shown, the antenna 100 of the present invention includes a first dielectric substrate 1, a first metal sheet 4 and a second metal sheet 7 attached to opposite surfaces of the first dielectric substrate 1, and a first metal sheet 4 is arranged around the first metal sheet 4. The feeder 2 is provided with a second feeder 8 around the second metal sheet 7, and the first feeder 2 and the second feeder 8 are respectively fed into the first metal sheet 4 and the second metal sheet 7 by means of coupling. A first microgroove structure 41 is hollowed out on the first metal sheet 4 to form a first metal trace 42 on the first metal sheet, and a second microgroove structure 71 is hollowed out on the second metal sheet 7 to form a first metal trace 42 on the second metal sheet. A second metal wire 72 is formed, and the first feeder 2 is electrically connected to the second feeder 8 . This design is equivalent to increasing the physical length of th...
