Electronic Device

摘要

A small electronic device enables improving transmission and reception performance with stable operation. An example of the electronic device is an electronic wristwatch having a display; a circuit board disposed on one side of the display; an antenna is disposed on the opposite side of the circuit board as the display, and includes a dielectric layer, a ground conductor disposed on one side of the dielectric layer, and a radiating conductor disposed on the other side of the dielectric layer. The ground conductor is disposed on the surface of the dielectric layer on the side near the circuit board, and is connected to the ground potential of the circuit board. The radiating conductor is disposed on the surface of the dielectric layer on the side far from the circuit board, and is connected to the signal potential of the circuit board.
