1. An ultra-wideband (UWB) antenna comprising:
a dielectric substrate comprising a first surface and a second surface;
a first conductive layer on the first surface of the dielectric substrate, the first conductive layer comprising a first patch antenna, a second patch antenna, a third patch antenna, a first transmission line, a second transmission line, a third transmission line, and a connector; and
a second conductive layer on the second surface of the dielectric substrate,
wherein the first patch antenna comprises a structure configured to receive a first UWB signal of a first frequency band in which a polarity direction of an electric field of the first UWB signal is a vertical linear polarization, and a second UWB signal of a second frequency band in which a polarity direction of an electric field of the second UWB signal is a horizontal linear polarization,
wherein the second patch antenna is spaced apart from the first patch antenna in a first direction and comprises a structure identical to the structure of the first patch antenna,
wherein the third patch antenna is spaced apart from the first patch antenna in a second direction perpendicular to the first direction and comprises a structure identical to the structure of the first patch antenna,
wherein the first transmission line is configured to connect the connector and the first patch antenna, the second transmission line is configured to connect the connector and the second patch antenna, and the third transmission line is configured to connect the connector and the third patch antenna, and
wherein the second conductive layer comprises a ground pattern which overlaps with 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.
