Abstract: An earbud according to an embodiment may comprise: a housing which includes a main body portion having a speaker port and a stalk extending from the main body portion; and an antenna structure which is disposed in the stalk and radiates a wireless signal to the outside of the earbud. The antenna structure may comprise: an antenna pattern which is connected to a power supply part and formed to have a first length so as to radiate the signal; and a ground pattern which is connected to a ground pattern of the PCB and formed to surround the antenna pattern on one side and the other side of the antenna pattern.

Abstract: According to one embodiment of the present specification, a user terminal is provided. The user terminal can comprise: a tunable antenna capable of adjusting a band; a diplexer connected to the tunable antenna to synthesize and separate sub-carriers; one or more antenna switches connected to the diplexer to synthesize and separate low-band sub-carriers and middle-band and high-band sub-carriers; and a sub-carrier processing unit connected to the one or more antenna switches to synthesize and separate a plurality of low-band sub-carriers, a plurality of middle-band sub-carriers and a plurality of high-band sub-carriers. A low-noise amplifier can be connected to the sub-carrier processing unit in order to prevent an increase in a reception sensitivity loss and a noise index occurring on a reception path of the diplexer, the one or more antenna switches and the sub-carrier processing unit.
