Abstract: An antenna device includes: a dielectric layer including a first edge extending in a first direction and a second edge, shorter that the first edge, extending in a second direction; a first feed via penetrating a portion of the dielectric layer in a third direction, and disposed adjacent to the second edge; a second feed via penetrating a portion of the dielectric layer in the third direction, disposed adjacent to the first edge; a feed pattern connected to the second feed via; and an antenna patch disposed on the second feed via and the feed pattern in the third direction, and coupled to the first feed via, the second feed via, and the feed pattern. The antenna patch overlaps the first feed via in a direction parallel to the first direction or the second direction. The antenna patch overlaps the feed pattern in a direction parallel to the third direction.

Abstract: Disclosed herein is a digitizer, including: an input unit in which a magnet is embedded; a driving coil in which source supplies to induce a line of magnetic force; a sensing coil in which voltage or current is induced by the line of magnetic force; and a controlling unit supplying the source to the driving coil and measuring the voltage or the current induced in the sensing coil, wherein the controlling unit senses a change amount in the voltage or the current induced in the sensing coil to calculate a coordinate, when the voltage or the current induced in the sensing coil is changed by the magnet.
