    Abstract: A terminal is disclosed by the present specification. The terminal may comprise: an antenna; a diplexer for compounding a carrier of a first band and a carrier of a second band and for connecting or disconnecting the same to the antenna; a filter connected to the diplexer, a first duplexer connected to the filter for separating transmissions and receptions in the carrier of the first band; and a second duplexer connected to the diplexer for separating transmissions and receptions in the carrier of the second band. To this end, the filter can eliminate harmonic components and intermodulation distortions (IMD) that occur when transmission in the carrier of the first band and transmission in the carrier of the second band are simultaneously performed.

    Abstract: This electronic device comprises: a main frame disposed along a peripheral region of a display and extending along a side region and a rear region of the electronic device; and an antenna module disposed in an inner space of the main frame and configured to radiate a radio signal in a forward direction or a downward direction of the electronic device through the main frame. The antenna module comprises: a first dielectric layer disposed spaced apart from one side of the antenna substrate in a first direction in which antenna elements radiate signals; a second dielectric layer disposed spaced apart from the first dielectric layer in the first direction; and an air gap layer disposed between the first dielectric layer and the second dielectric layer.

    Abstract: Provided is an electronic device having an antenna according to an embodiment. The electronic device may comprise a first and a second ground plane arranged on different layers of a multi-layer substrate and configured to be connected to each other through vias spaced a predetermined distance apart from each other. The electronic device may comprise a signal line arranged on the same plane as the first ground plane which is disposed at the upper side among the first and the second ground plane. The electronic device may comprise a radiator configured to be electrically connected to the signal line and emit a signal. The first ground plane may be disposed at only one region of one side region and the other side region of the signal line in a predetermined section.

    Abstract: There is provided a method for limiting a spurious emission, the method performed by a user equipment (UE). The method may comprise: if a radio frequency (RF) unit of the UE is configured to use a 3GPP standard based E-UTRA band 1, configuring a RF unit of the UE to limit a maximum level of spurious emission to −50 dBm for protecting other UE using a 3GPP standard based E-UTRA band 5 in order to apply a UE-to-UE coexistence requirement for the same region to inter-regions; if the RF unit is configured to use the 3GPP standard based E-UTRA band 5, configuring the RF unit of the UE to limit a maximum level of spurious emission to −50 dBm for protecting other UE using at least one of the 3GPP standard based E-UTRA bands 1, 3, 7, 8, 38, 40 in order to apply a UE-to-UE coexistence requirement for the same region to inter-regions; and transmitting an uplink signal through the configured RF unit.
