Dual-polarized antenna and related antenna module and electronic device

An antenna, comprising:

• a ground layer;
• a first coupling metal disposed on a first region over the ground layer;
• a second coupling metal disposed on a second region over the ground layer;
• a third coupling metal disposed on a third region over the ground layer;
• a fourth coupling metal disposed on a fourth region over the ground layer, wherein the first coupling metal, the second coupling metal, the third coupling metal and the fourth coupling metal define the first region, the second region, the third region, the fourth region, a first channel, a second channel, a third channel, a fourth channel and a center region over the ground layer;
• a first polarization signal feeding terminal and a second polarization signal feeding terminal disposed over the ground layer;
• a first polarization structure having a first extending portion electrically connected to the first polarization signal feeding terminal and extending from the first channel to the second channel in a first direction on the center region over the ground layer;
• a second polarization structure having a second extending portion electrically connected to the second polarization signal feeding terminal and extending from the third channel to the fourth channel in second direction on the center region over the ground layer, wherein the first extending portion crosses the second extending portion in a non-contact manner to define the first region, the second region, the third region and the fourth region;
• a first radiating metal disposed on the first channel;
• a second radiating metal disposed on the second channel;
• a third radiating metal disposed on the third channel;
• and
• a fourth radiating metal disposed on the fourth channel.
