Specifically, referring to fig. 9 and 10 together, fig. 9 is another schematic structural diagram of the second substrate according to an embodiment of the present disclosure, and fig. 10 is an enlarged view of the antenna element in a position a in fig. 9. The outer surface of the periphery of the frame 521 is formed with a groove, and the groove extends from the outer periphery of the frame 521 toward the inner surface of the frame 521.
