a bezel surface formed on a boundary of the display panel; and an antenna located on the bezel surface, wherein the antenna comprises: an antenna body extending in a horizontal direction to the bezel surface; an extension body provided on one side or opposite sides of the antenna body; and a frequency variable device configured to selectively electrically connect the antenna body and the extension body, wherein the antenna body comprises: a first body extending in a first direction along the bezel surface; a second body extending along the bezel surface in a second direction opposite to the first direction; and a connection body connecting the first body and the second body, and wherein a width of the connection body is smaller than a width of the first body or the second body. ### Claim 2 (depends on 1) The display apparatus according to claim 1, wherein the frequency variable device comprises a pin diode configured to electrically connect the antenna body and the extension body as power is supplied. ### Claim 3 (depends on 2) The display apparatus according to claim 2, wherein the antenna is configured to operate at a first frequency when power supplied to the pin diode is cut off, and wherein the antenna is configured to operate at a second frequency lower than the first frequency when power is supplied to the pin diode. ### Claim 4 (depends on 1) The display apparatus according to claim 1, wherein the frequency variable device comprises a varactor diode configured to adjust a degree of electrical connection between the antenna body and the extension body. ### Claim 5 (depends on 4) The display apparatus according to claim 4, wherein an operating frequency of the antenna is configured to gradually increase as power supplied to the varactor diode increases. ### Claim 6 (depends on 1) The display apparatus according to claim 1, further comprising a bottom chassis configured to cover the rear of the display panel, wherein the antenna comprises a power supply portion extending from one portion of the antenna body, and a ground portion extending from the other portion of the antenna body and connected to the bottom chassis. ### Claim 7 (depends on 6) The display apparatus according to claim 6, wherein the bottom chassis comprises metal. ### Claim 8 (depends on 1) The display apparatus according to claim 1, wherein the connection body comprises a power supply portion to which current is applied, and the antenna body comprises a first ground portion extending from the first body and a second ground portion extending from the second body. ### Claim 9 (depends on 1) The display apparatus according to claim 1, wherein the antenna body is configured to have: a first resonant frequency formed by a first current flowing in the first direction along the first body and a second current flowing in the second direction along the second body; and a second resonant frequency formed by a third current sequentially flowing through the first body, the connection body, and the second body, wherein the second resonant frequency is different from the first resonant frequency. ### Claim 10 (depends on 1) The display apparatus according to claim 1, wherein the antenna comprises an inductor disposed on the extension body. ### Claim 11 (depends on 1) The display apparatus according to claim 1, wherein the antenna is formed on at least one of an upper surface, a left surface, and a right surface of the bezel surface. ### Claim 12 (depends on 1) The display apparatus according to claim 1, wherein the antenna body is disposed on the same surface as the bezel surface.
