Abstract
An antenna is provided. The antenna includes a substantially transparent base substrate; a first pattern having a first feed point and a second pattern having a second feed point spaced apart from each other; a first feed line electrically connected to the first pattern through the first feed point; and a second feed line electrically connected to the second pattern through the second feed point. A first width along a first direction, of the first pattern, gradually increases along a second direction. A second width along the first direction, of the second pattern, gradually increases along a third direction substantially opposite to the second direction. A third width along a fourth direction, of the first feed line, gradually increases along a fifth direction. A fourth width along a sixth direction, of the second feed line, gradually increases along a seventh direction.
