Abstract

See full text

An antenna structure according to an embodiment of the present invention includes a film antenna including a dielectric layer, an upper electrode layer disposed on an upper surface of the dielectric layer and including a radiation pattern, a transmission line, and a ground pad, and a lower ground layer disposed on a lower surface of the dielectric layer, and a flexible circuit board including a core layer, a power supply wiring layer disposed on a lower surface of the core layer and electrically connected to the transmission line, and a ground plate disposed on an upper surface of the core layer and disposed in overlapping with the power supply wiring layer in a planar direction. Thereby, it is possible to reduce a radiation signal generated from the power supply wiring through the ground plate, suppress a noise of the antenna and increase radiation efficiency.
