Antenna module
First 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;
whereinthe 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.

Abstract
In an antenna module, a main portion includes a plurality of insulating sheets made of a flexible material and laminated on each other. An antenna configured to transmit/receive a high-frequency signal is disposed in the main portion. A connection portion is disposed in the main portion and is connected to an electronic device that inputs/outputs the high-frequency signal. A signal transmission line is disposed in the main portion and has a strip line structure or a microstrip line structure to transmit the high-frequency signal. An impedance matching circuit is disposed in the main portion and between the antenna and end of a signal transmission line facing in a negative x direction. An impedance matching circuit is disposed in the main portion and between the connection portion and an end of the signal transmission line facing in a positive x direction.
