Claim:
1. An antenna module comprising: a main portion including a lamination of a plurality of flexible insulating sheets, the main portion including an antenna region, a signal transmission line region, and a connection region; an antenna disposed on the main portion in the antenna region and configured to transmit/receive a high-frequency signal; a connection portion disposed on the main portion in the connection region and configured to be connected to an electronic device that outputs/inputs the high-frequency signal; a signal transmission line configured to transmit the high-frequency signal, the signal transmission line being disposed in the main portion in the signal transmission line region and having a strip line structure or a microstrip line structure; a first impedance matching circuit disposed in the antenna region; and a second impedance matching circuit disposed in the connection region; wherein the plurality of flexible insulating sheets include and define the antenna region, the signal transmission line region, and the connection region; no impedance matching circuits are disposed in the signal transmission line region; the antenna region, the signal transmission line region, and the connection region are arranged in this order along a longitudinal direction of the main portion; a width of the signal transmission line region extending in a direction perpendicular or substantially perpendicular to the longitudinal direction is less than a width of the antenna region extending in the direction perpendicular or substantially perpendicular to the longitudinal direction and is less than a width of the connection region extending in the direction perpendicular or substantially perpendicular to the longitudinal direction; the first impedance matching circuit includes a line-shaped conductor and a ground conductor, and does not include any chip elements; and the second impedance matching circuit includes at least one of a chip capacitor and a chip coil.
