Abstract: An electronic device according to the present invention comprises: a first multi-layer printed circuit board (PCB) including a transceiver circuit; a second multi-layer PCB including an antenna; and a connector configured to connect the first multi-layer PCB and the second multi-layer PCB to each other, wherein the first and the second multi-layer PCB include signal transmission lines configuring a vertical connection for signal transfer between different layers, and include multiple adjacent ground patterns configuring a vertical ground connection between the different boards. In order to improve the matching characteristic between the vertically connected signal transmission lines, window regions from which a metal pattern is eliminated are formed at the same positions in different layers of the first and the second multi-layer PCB between the adjacent ground patterns. Therefore, the present invention can provide the connector and the electronic device providing an optimal matching characteristic in vertically connecting the antenna and the transceiver circuit in mmWave bands.

Abstract: Provided is a method for transmitting and receiving a signal by a terminal supporting dual-connectivity between evolved universal terrestrial radio access (E-UTRA) and new radio (NR). In the method, when the terminal is configured to aggregate at least two carriers and when the at least two carriers include one of E-UTRA operating bands 1, 3, 19, and 21 and at least one of NR operating bands n78 and n79, an uplink center frequency of a first carrier among the at least two carriers is a first value and a downlink center frequency of the first carrier is a second value, a predetermined maximum sensitivity degradation (MSD) is applied to a reference sensitivity used for reception of the downlink signal.

Abstract: An electronic device with an antenna, according to the present invention, has a cone antenna comprising: a cone radiator which is provided between a first substrate and a second substrate, has the upper part thereof connected to the first substrate and the lower part thereof connected to the second substrate, and has an opening at the upper part; a metal patch formed on the first substrate and spaced apart from the upper opening; and a shorting pin formed to electrically connect the metal patch and a ground layer of the second substrate. The electronic device may further comprise a transceiver circuit which is connected to the cone radiator via a feed and controls so as to radiate a signal via the cone antenna. Accordingly, the size of the entire antenna can be minimized by arranging the metal patch on only one side of the upper opening of the cone antenna.
