Antenna structure including parasitic conductive plate

An antenna structure comprising:

• at least one feeder;
• a first layer connected to the at least one feeder, the first layer comprising a first conductive plate;
• a second layer disposed on a front face of the first layer, the second layer comprising a second conductive plate;
• a third layer disposed on a front face of the second layer, the third layer comprising a third conductive plate;
• and
• a fourth layer disposed on a front face of the third layer, the fourth layer comprising a radiator electrically connected to the at least one feeder through conductive vias,
• wherein the radiator comprises:
• a plurality of first parasitic conductive plates spaced apart from each other, and
• a second parasitic conductive plate disposed between the plurality of first parasitic conductive plates, the second parasitic conductive plate being spaced apart from the plurality of first parasitic conductive plates.

An electronic device comprising:

• a housing;
• a printed circuit board disposed within the housing;
• a processor mounted on the printed circuit board;
• and
• an antenna structure disposed inside or outside of the housing,
• wherein the antenna structure comprises:
• a feeder,
• a dielectric substrate,
• an array of first parasitic conductive plates disposed on the dielectric substrate to be spaced apart from each other,
• a second parasitic conductive plate disposed in a center of the array of first parasitic conductive plates,
• first line conductors disposed to be in contact with the second parasitic plate, and
• second line conductors disposed perpendicular to the first line conductors, respectively, and the second line conductors are disposed in respective edges of the dielectric substrate.
