1. An antenna, comprising:
a printed circuit board (PCB);
a first antenna; and
a second antenna;
wherein the first antenna is partially or entirely printed in a rectangular region of a first surface of the PCB, and is configured to respond to an electromagnetic wave of a first band, and the second antenna is entirely printed in the rectangular region, and is configured to respond to an electromagnetic wave of a second band;
wherein the first antenna comprises a first feeding portion and at least one stub;
wherein the first feeding portion is disposed on a first side of a first diagonal line of the rectangular region, and is configured to perform mutual conversion between the electromagnetic wave of the first band and a wired signal, wherein the at least one stub of the first antenna extends from the first feeding portion in a first direction, and wherein a first angle is disposed between the first direction and a long-edge direction of the rectangular region;
wherein the second antenna comprises a second feeding portion and at least one stub; and
wherein the second feeding portion is disposed on a second side of the first diagonal line of the rectangular region, wherein the second feeding portion is configured to perform mutual conversion between the electromagnetic wave of the second band and a wired signal, wherein the at least one stub of the second antenna extends from the second feeding portion in a second direction, wherein a second angle is disposed between the second direction and the long-edge direction of the rectangular region, and wherein the first angle is different from the second angle.
