Wireless communication module

A wireless communication module, comprising:

• a substrate, having a lateral surface;
• a first antenna, adjacent to the lateral surface of the substrate;
• a second antenna, adjacent to the lateral surface of the substrate, wherein a connection direction between the first antenna and the second antenna is parallel to the lateral surface;
• a first resonator group and a second resonator group, disposed between the first antenna and the second antenna and separated from the first antenna and the second antenna along a direction perpendicular to the lateral surface, wherein the first resonator group is adjacent to the first antenna and comprises:
• a first resonator, adjacent to the lateral surface and comprising a first resonant cavity, a first extension slot, a first conductive portion and a second conductive portion, wherein the first extension slot extends towards the lateral surface of the substrate from the first resonant cavity and forms an opening on the lateral surface, and the first conductive portion and the second conductive portion are located within the first resonant cavity and separated from each other;
• and
• a second resonator, separated from the first resonator along a direction perpendicular to the lateral surface and comprising a second resonant cavity and a second extension slot, wherein the second extension slot extends towards the lateral surface of the substrate from the second resonant cavity and is separated from the first resonant cavity of the first resonator, wherein the first resonator is disposed between the lateral surface and the second resonator;
• wherein the second resonator group is disposed between the first resonator group and the second antenna and comprises:
• a third resonator, adjacent to the first resonator group and comprising a third resonant cavity, a third extension slot, a third conductive portion and a fourth conductive portion, wherein the third extension slot extends towards the lateral surface of the substrate from the third resonant cavity and is separated from the second resonant cavity of the second resonator, and the third conductive portion and the fourth conductive portion are located within the third resonant cavity and separated from each other;
• a fourth resonator, separated from the third resonator along a direction perpendicular to the lateral surface and comprising a fourth resonant cavity and a fourth extension slot, wherein the fourth extension slot extends towards the lateral surface of the substrate from the fourth resonant cavity and is separated from the third resonant cavity of the third resonator, wherein the third resonator is disposed between the lateral surface and the second resonator group.
