Antenna module and electronic device including the same

An electronic device comprising:

• at least one processor comprising processing circuitry;
• wireless communication circuitry coupled to at least one processor;
• and
• an antenna module coupled to the wireless communication circuitry,
• wherein the antenna module includes:
• a circuit board on which a first radiator array for a first frequency band, a second radiator array for a second frequency band higher than the first frequency band, and a third radiator array for a third frequency band lower than the first frequency band are disposed,
• wherein the first radiator array includes patch radiators having a first size, disposed on a first layer among a plurality of layers of the circuit board,
• wherein the second radiator array includes patch radiators having a second size smaller than the first size, disposed on a second layer above the first layer with respect to a side of the circuit board among the plurality of layers of the circuit board,
• wherein the third radiator array includes patch radiators having a third size larger than the first size, disposed on a third layer below the first layer with respect to the side of the circuit board among the plurality of layers of the circuit board,
• wherein the patch radiators disposed on the second layer of the circuit board are disposed to overlap the patch radiators disposed on the first layer of the circuit board, respectively,
• wherein the patch radiators disposed on the third layer of the circuit board include a patch radiator having a first patch portion partially overlapping one of two adjacent patch radiators among the patch radiators disposed on the first layer of the circuit board and a second patch portion partially overlapping another of the two adjacent patch radiators, and
• wherein a gap between the first patch portion and the second patch portion is disposed on an area between the two adjacent patch radiators.
