## Abstract

An electronic device may include a wireless communication circuitry, an antenna device to transmit or receive a signal associated with an operation of the wireless communication circuitry. The antenna device may include a ground layer, at least one antenna radiator disposed at an upper portion of the ground layer, a first cell layer in which a plurality of conductive cells having a first size and shape are repeatedly disposed, with a specific distance, at a peripheral portion of the at least one antenna radiator, and a second cell layer in which a plurality of conductive cells having a second size and shape are disposed with a specific distance at a lower portion of the first cell layer and at the peripheral portion of the at least one antenna radiator. Moreover, various embodiment found through the disclosure are possible.

## Claims

### Claim 1

An electronic device comprising:
a housing including a first plate, a second plate facing away from the first plate, and a side member surrounding a space between the first plate and the second plate;
an antenna assembly including:
a plurality of planes disposed in parallel to the second plate, and stacked on each other, wherein the planes include:
a first plane interposed between the first plate and the second plate;
a second plane interposed between the first plane and the first plate; and
a third plane interposed between the second plane and the first plate;
a first conductive plate disposed in parallel to the planes and interposed between the first plane and the first plate within a first area, when viewed from above the second plate;
conductive islands having a first repeating pattern and disposed on the first plane within a second area surrounding the first area, when viewed from above the second plate;
conductive islands disposed on the second plane within the second area, and having a second repeating pattern partially overlapped with the first repeating pattern, when viewed from above the second plate;
conductive islands disposed on the third plane within the second area, and having a third repeating pattern partially overlapped with the second repeating pattern, when viewed from above the second plate; and
a wireless communication circuitry disposed in the space, electrically connected with the first conductive plate, and configured to supply a signal having a frequency range of 3 GHz to 300 GHz.

### Claim 2 (depends on 1)
