Abstract: A horn antenna for a millimeter wave comprises: a horn radiator including a radiation part having an opening formed therein to radiate a feed signal, and a multi-layer PCB coupling part coupled to lower and side portions of the radiation part to provide a feed signal; and a multi-layer PCB coupled to a lower portion of the multi-layer PCB coupling part to provide a feed signal, wherein a slot and a groove connected to the slot and extending in a direction parallel to the multi-layer PCB are formed in the multi-layer PCB coupling part, wherein a feed line vertically overlapping the slot and the groove is formed on a first layer substrate, which is the uppermost layer of the multi-layer PCB, wherein the opening extends in a direction parallel to the multi-layer PCB, and wherein a ‘¬’-shaped waveguide extending from the slot is formed in the horn radiator.
