Abstract: A loop antenna unit including two loop antennas having a same number of turns and different winding directions, the two loop antennas being positioned in line symmetry and not superposed on each other in a plan view. Each of the two loop antennas includes a loop conductive line wound continuously in one direction with n turns, where n is an integer of 3 or more, forming loops from a start point to an end point on the outermost loop or the innermost loop, the loop conductive line being bent in a transitional region in a direction from an outer loop toward an inner loop such that the loops have bent portions positioned side by side from an outermost first loop to an (n−1)th loop in the transitional region, and a jumper wire positioned on the insulating layer to cross the transitional region in a plan view.

Abstract: An electronic device includes first, second and third substrates positioned in this order when viewed in an observation direction, antenna units including first, second, third, and fourth antenna units formed such that the first and second antenna units are positioned on opposite sides of the second substrate and superposed on each other in the plan view, and that the third and fourth antenna units are positioned on the opposite sides of the second substrate and superposed on each other in the plan view, a display functional layer formed between the first and second substrates, a touch sensing functional layer formed between the first and second substrates, and including a capacitive touch sensing wiring unit and the first antenna unit, and a controller which is formed on the third substrate and controls a touch sensing function, a display function, a communication function, and a wireless charging function of the device.
