1. An antenna, comprising:
a ground plate, and a slot extending through the ground plate;
a first dielectric layer on the ground plate and the slot;
a microstrip feed line and a first radiating patch on a side of the first dielectric layer away from the ground plate, the first radiating patch being coupled to the microstrip feed line and configured to receive a signal from the microstrip feed line;
a second dielectric layer on a side of the ground plate and the slot away from the first dielectric layer, the first radiating patch, and the microstrip feed line; and
a second radiating patch on a side of the second dielectric layer away from the ground plate, the second radiating patch being configured to receive a signal by aperture coupling through the slot;
wherein the slot has a shape comprising, sequentially along a first direction, a first rectangular shape, a first trapezoidal shape, a second trapezoidal shape, and a second rectangular shape;
short sides of the first trapezoidal shape and the second trapezoidal shape are connected to each other; and
along a second direction perpendicular to the first direction, lengths of the first rectangular shape and the second rectangular shape are substantially the same as lengths of long sides of the first trapezoidal shape and the second trapezoidal shape.
