Wearable device and communication method

A wearable device, comprising:

• a first antenna element, receiving a first wireless signal;
• a second antenna element, receiving a second wireless signal;
• a third antenna element, receiving a third wireless signal;
• a first phase shifter, coupled to the first antenna element, wherein the first phase shifter provides a first compensation phase for the first wireless signal;
• a second phase shifter, coupled to the second antenna element, wherein the second phase shifter provides a second compensation phase for the second wireless signal;
• a third phase shifter, coupled to the third antenna element, wherein the third phase shifter provides a third compensation phase for the third wireless signal;
• a signal combiner, coupled to the first phase shifter, the second phase shifter, and the third phase shifter, wherein the signal combiner generates an integrated signal according to the first wireless signal, the second wireless signal, and the third wireless signal;
• and
• a carrier element, wherein the first antenna element, the second antenna element, and the third antenna element are disposed on the carrier element and are arranged along different directions.
