1. An antenna, comprising:
a ground plate;
a dielectric layer on the ground plate; and
a microstrip feed line and a radiating patch on a side of the dielectric layer away from the ground plate, the radiating patch being coupled to the microstrip feed line and configured to receive a signal from the microstrip feed line;
wherein the radiating patch comprises a main body having a parallelogram shape with a first notch truncating a corner of the parallelogram shape, at least a portion of the main body truncated by the first notch having an arc-shaped contour line; and
the radiating patch further comprises a first branch structure disconnected from the microstrip feed line;
wherein the main body is asymmetric;
the first notch does not have a symmetric counterpart with respect to an axis or a plane perpendicular to the main body and intersecting the main body and the ground plate; and
the first branch structure does not have a symmetric counterpart with respect to an axis or a plane perpendicular to the main body and intersecting the main body and the ground plate.
