    Abstract: Example embodiments include an electronic device and a method for operating an electronic device. The electronic device includes an ultra-wide band (UWB) antenna including directional antennas disposed on a rear surface of the electronic device and at least one omnidirectional antenna. The electronic device further includes a communication circuit configured to transmit and/or receive radio frequency (RF) signals of a frequency band designated to be used for UWB communication, through the UWB antenna, with an external electronic device. The electronic device further includes a processor configured to calculate a first distance value and a second distance value, and to determine, based on a distance difference between the first distance value and the second distance value, whether the external electronic device exists within a field of view (FoV) indicating a specified angular range with respect to the direction to which the rear surface faces.

    Abstract: An image sensor is provided and includes a photoelectric conversion layer, an integrated circuit layer, and a charge storage layer. The photoelectric conversion layer includes a pixel separation structure defining pixel regions, each including a photoelectric conversion region. The integrated circuit layer read charges from the photoelectric conversion regions. The charge storage layer includes a stacked capacitor for each of the pixel regions. The stacked capacitor includes a lower pad electrode, an intermediate pad electrode, an upper pad electrode, a contact plug connecting the upper pad electrode to the lower pad electrode, a first lower capacitor structure connected between the lower pad electrode and the intermediate pad electrode, and an upper capacitor structure connected between the intermediate pad electrode and the upper pad electrode. The upper capacitor structure is stacked on the lower capacitor structure to partially overlap the lower capacitor structure when viewed in plan view.

    Abstract: An electronic device is provided. The electronic device includes an antenna and an ultra wide band (UWB) communication circuit connected with the antenna. The UWB communication circuit is configured to filter a positioning signal received from the antenna into a specified band to be converted into a digital signal, generate a UWB packet including a first field associated with synchronization and a second field associated with security, obtain a first channel impulse response corresponding to the first field and a second channel impulse response corresponding to the second field, when the UWB packet is valid based on the second field, obtain a third channel impulse response, when there is a correlation between the first channel impulse response and the second channel impulse response, and measure a distance to the external electronic device based on the third channel impulse response.
