Abstract: An antenna structure may include a transmission antenna unit group, and a reception antenna unit group spaced apart from the transmission antenna unit group in a first direction. The transmission antenna unit group includes a first transmission antenna unit, and a second transmission antenna unit having a length in a second direction greater than a length of the first transmission antenna unit in the second direction, the second direction being perpendicular to the first direction. The reception antenna unit group includes a first reception antenna unit spaced apart from the first transmission antenna unit in the first direction and including a first reception radiator, and a second reception antenna unit including a second reception radiator spaced apart the first reception radiator in the second direction.

Abstract: An antenna structure may include a transmission antenna unit group, and a reception antenna unit group spaced apart from the transmission antenna unit group in a first direction. The transmission antenna unit group includes a first transmission antenna unit and a second transmission antenna unit having a length in a second direction greater than a length of the first transmission antenna unit in the second direction, the second direction being perpendicular to the first direction. The reception antenna unit group includes a plurality of reception antenna units spaced apart from the first transmission antenna unit in the first direction and being arranged in a single row.

Abstract: A circuit board includes a core layer, a first via structure penetrating the core layer, a circuit wiring disposed on one surface of the core layer and including a head portion in contact with the first via structure, a connection portion extending from the head portion and an extension portion electrically connected to the head portion through the connection portion, and a first ground pattern disposed on the one surface of the core layer and disposed around the circuit wiring to be spaced apart from the circuit wiring. A shortest distance between the extension portion and the first ground pattern is greater than a shortest distance between the head portion and the first ground pattern.
