Coupled antenna module

A coupled antenna module, comprising:

• an antenna carrying substrate having an upper surface, a lower surface, a first side surface, a second side surface, a third side surface and a fourth side surface;
• a first antenna structure disposed on the upper surface, the lower surface and the first side surface of the antenna carrying substrate;
• and
• a second antenna structure disposed on the upper surface, the lower surface and the second side surface of the antenna carrying substrate;
• wherein the first antenna structure has a first radiation layer disposed on the upper surface of the antenna carrying substrate, a first extension layer disposed on the first side surface of the antenna carrying substrate, and a first conductive layer disposed on the lower surface of the antenna carrying substrate;
• wherein the second antenna structure has a second radiation layer disposed on the upper surface of the antenna carrying substrate, a second extension layer disposed on the second side surface of the antenna carrying substrate, and a second conductive layer disposed on the lower surface of the antenna carrying substrate;
• wherein the first radiation layer of the first antenna structure has a first base portion, a first extending portion extending from the first base portion toward the second side surface, and a first bending portion bending from the first extending portion toward the third side surface;
• and
• wherein the second radiation layer of the second antenna structure has a second base portion, a second extending portion extending from the second base portion toward the first side surface, and a second bending portion bending from the second extending portion toward the fourth side surface.
