Figure 1 illustrates an example of an environment including an electronic device including an antenna element. Referring to FIG. 1, the environment (150) may include an electronic device (100) and an external electronic device (110). For example, the electronic device (100) may be used to radiate electromagnetic waves or signals. For example, the electronic device (100) may be used to receive electromagnetic waves or signals. For example, the electronic device (100) may transmit a signal to the external electronic device (110). For example, the electronic device (100) may receive a signal from the external electronic device (110). For example, the electronic device (100) may transmit or receive the signal using an antenna included in the electronic device (100). For example, the state (130) may be described as an array antenna (140) included within the electronic device (100). For example, the array antenna (140) may include a patch antenna. For example, the array antenna (140) may include a microstrip patch antenna. For example, the array antenna (140) may include a coaxial feed patch antenna. For example, the electronic device (100) can transmit or receive signals through an antenna. For example, the electronic device (100) can use high-frequency electromagnetic waves for miniaturization. For example, the higher the frequency of the electromagnetic waves radiated through the antenna of the electronic device (100), the smaller the size of the antenna of the electronic device (100). For example, the higher the frequency of the electromagnetic waves, the shorter the wavelength of the electromagnetic waves, so less diffraction of the electromagnetic waves may occur. For example, when the antenna of the electronic device (100) radiates high-frequency electromagnetic waves, the electronic device (100) may use multiple antennas to increase the distance over which the electromagnetic waves reach. For example, when the electronic device (100) radiates high-frequency electromagnetic waves, an array antenna (140) may be used to increase the distance over which the electromagnetic waves reach. For example, the electronic device (100) can cause the battery of an external electronic device (110) to be charged by transmitting a power signal. For example, the battery of the external electronic device (110) can be charged by the power signal received from the electronic device (100). For example, the electronic device (100) can radiate a power signal through an antenna to charge a small external electronic device (110). For example, the electronic device (100) can radiate a power signal to charge the battery of an external electronic device (110) located within a specific distance (e.g., 5 m). For example, the power consumed by the external electronic device (110) charged by the power signal may be less than a threshold power (e.g., 1 W). For example, the structure of an antenna for transmitting a power signal to the external electronic device (110) located within the specific distance may be required. For example, an antenna structure may be required for high-frequency electromagnetic waves (e.g., 2.4 GHz and 5.8 GHz) radiated by an elec
