Classification: CPC H | IPC H

Claim 14:
15. An antenna module comprising:
a flexible substrate having a plate shape; and
an output terminal connected to the first line and the second line of the flexible substrate and configured to output a signal to an external feeding element,
wherein the flexible substrate having the plate shape comprises:
a first surface;
a second surface opposed to the first surface; and
a first line provided on the first surface or in a layer between the first surface and the second surface;
a second line provided on the second surface or in a layer between the second surface and the first line; and
a ground electrode provided in a layer between the first line and the second line so as to extend in the layer between the first surface and the second surface,

wherein the ground electrode forms a first radio frequency transmission line together with the first line and forms a second radio frequency transmission line together with the second line, and
under a condition the flexible substrate is seen through from a thickness direction of the flexible substrate, the first line has a line-symmetrical portion that is line-symmetrical with respect to the second line with a virtual intermediate line between the first line and the second line serving as a symmetric line.
