    Abstract: According to various embodiments disclosed in the present document, an antenna module and/or an electronic device including same may comprise: a communication circuit part; an antenna part stacked-up on or above the communication circuit part and comprising multiple antenna elements; and a network part disposed between the communication circuit part and the antenna part. The antenna part may comprise: at least one first subarray formed of a combination of some of the antenna elements; and at least one second subarray formed of a combination another of the antenna elements, and disposed to be point symmetric to the first subarray. The network part may comprise: a first transmission port corresponding to a transmission input terminal of the first subarray; a first reception port corresponding to a reception input terminal of the first subarray; a second transmission port corresponding to a transmission input terminal of the second subarray; and a second reception port corresponding to a reception input terminal of the second subarray. With respect to symmetric points of the first subarray and the second subarray, the first transmission port may be disposed to be point symmetric to the second reception port, and the first reception port may be disposed to be point symmetric to the second transmission port. Various other embodiments are possible.

    Abstract: The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A spatial filter is provided. The spatial filter includes a first substrate having a first parasitic element configured to provide a filtering function and disposed on the spatial filter device, a second substrate having a second parasitic element configured to provide a filtering function and disposed under the spatial filter device, and a dipole antenna configured to transmit and receive radio waves in free space, coupled to each of the first parasitic element and the second parasitic element so as not to be aligned therewith, and disposed between the first substrate and the second substrate.

    Abstract: A 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A reconfigurable intelligent surface (RIS) including a plurality of unit cells in a wireless communication system includes a first pattern included in a top layer of a unit cell included in the RIS, a second pattern included in a bottom layer of the unit cell included in the RIS, and at least one switch configured to electrically ground or short the first pattern and the second pattern in response to a command for determining whether the unit cell included in the RIS operates as a transmissive RIS or a reflective RIS.

    Abstract: The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A unit cell of a RIS includes a first conductive structure including a first element and a second element disposed under the first element; a second conductive structure including a third element and a fourth element disposed under the third element; and a switch circuit disposed between the first conductive structure and the second conductive structure. As a first RF signal from a first external device is incident on the unit cell, a second RF signal having a first resonance frequency is reflected based on electrical paths formed respectively in the first element and the third element, and a third RF signal having a second resonance frequency different from the first resonance frequency is reflected based on electrical paths formed respectively in the second element and the fourth element.
