Claim 21:
22. A radio frequency device comprising:
a base layer;
a first pattern portion disposed on the base layer, having a first characteristic impedance and a first mesh structure, and provided with a first opening;
a second pattern portion disposed on the base layer adjacent to the first pattern portion, having a second characteristic impedance different from the first characteristic impedance and a second mesh structure, and provided with a second opening; and
a third pattern portion disposed on the base layer, disposed adjacent to the second pattern portion, having a third characteristic impedance and a third mesh structure, and provided with a third opening, wherein the second characteristic impedance has a value between the first characteristic impedance and the third characteristic impedance, and
wherein a width of the first pattern portion is the largest among widths of the first, second, and third pattern portions, and the first characteristic impedance is the largest among the first, second, and third characteristic impedances,
wherein a width of the third pattern portion is equal to a width of the second pattern portion, and
wherein a shape of the second mesh structure is different from a shape of the third mesh structure.
