18. An antenna module implemented as a multi-layer substrate, the antenna module comprising:
a dielectric cavity formed as a hexahedron structure in which an air gap layer is implemented; and
an antenna substrate on which a plurality of antenna elements are arranged, wherein one side of the antenna substrate is spaced apart from a rear surface of the hexahedron structure,
wherein dielectric cavity comprises:
a first dielectric layer disposed spaced apart from one side surface of the antenna substrate in a first direction in which the plurality of antenna elements radiate signals;
a second dielectric layer disposed spaced apart from the first dielectric layer in the first direction;
first to fourth side surfaces configured to connect the first dielectric layer and the second dielectric layer and formed as side surfaces the antenna module; and
the air gap layer disposed between the first dielectric layer and the second dielectric layer,
wherein the first dielectric layer is provided to have a first width W1 in the first direction, the second dielectric layer is provided to have a second width W2 in the first direction, and the air gap layer is provided to have a particular gap G in the first direction,
wherein the first dielectric layer is formed as the rear surface of the dielectric cavity and the second dielectric layer is formed as a front surface of the dielectric cavity, and
wherein a radio signal radiated through the plurality of antenna elements has directivity toward a front direction through the dielectric cavity corresponding to the hexahedron structure.
