Terminal device

A terminal device, comprising feed sources, a metal frame, coupling patches, and radiating patches, wherein at least two grooves are formed in the outer side surface of the metal frame, two first through holes are formed in each groove, a coupling patch of the coupling patches and a radiating patch of the radiating patches are arranged in each groove, and the metal frame is grounded;

• the coupling patch in each groove is arranged between the radiating patch and the bottom of the groove, and two second through holes are formed in each coupling patch;
• two antenna feed points are arranged on each radiating patch, each feed source is connected to the corresponding antenna feed point of each two antenna feed points arranged on each radiating patch through the respective first through hole and the respective second through hole, and the antenna feed points, the first through holes, and the second through holes in each groove are in one-to-one correspondence;
• and the metal frame, the coupling patch, and the radiating patch are not in contact with one another, and a non-conductive material is filled between the metal frame, the coupling patch, and the radiating patch, and an area of the radiating patch is less than an area of the coupling patch;
• the feed source is a millimeter-wave feed source.
