1. A millimeter wave antenna, comprising:
a substrate, wherein the substrate comprises a first portion and a second portion, and a thickness of the first portion is less than a thickness of the second portion;
an antenna arranged on the substrate, wherein the antenna is arranged on the first portion only and is arranged on a first side of the first portion; and
a reference ground, attached to the substrate and arranged on the second portion only, wherein the reference ground is arranged a second side of the second portion away from the first side of the first portion,
wherein an orthographic projection of the reference ground onto a plane where the first side of the first portion is located is out of an orthographic projection of the antenna onto the plane where the first side of the first portion is located.
