UWB ANTENNA AND ELECTRONIC DEVICE INCLUDING SAME

An ultra wide band (UWB) antenna in various embodiments can comprise: a dielectric substrate; a first conductive layer arranged on one surface of the dielectric substrate; and a second conductive layer arranged on the other surface of the dielectric substrate. The first conductive layer can comprise: a first patch antenna having a structure of receiving a first UWB signal that has a first frequency band of which the polarity direction of the electric field is a vertical linear polarization, and a second UWB signal that has a second frequency band of which the polarity direction of the electric field is a horizontal linear polarization; a second patch antenna which is arranged to be spaced from the first patch antenna in a first direction and which has a structure that is the same as that of the first patch antenna; a third patch antenna which is arranged to be spaced from the first patch antenna in a second direction perpendicular to the first direction and which has a structure that is the same as that of the first patch antenna; a first transmission line for connecting a connector and the first patch antenna; a second transmission line for connecting the connector and the second patch antenna; and a third transmission line for connecting the connector and the third patch antenna. The second conductive layer can comprise a ground pattern, which overlaps on the first patch antenna, the second patch antenna, the third patch antenna, the first transmission line, the second transmission line, and the third transmission line, when facing the second conductive layer in a third direction that is perpendicular to the first direction and the second direction. Other various embodiments are possible.
