## Abstract

An antenna module includes: a substrate; at least one first communication antenna by a frequency band belonging to a first frequency range; and at least one second communication antenna by a frequency band belonging to a second frequency range higher than the first frequency range, wherein the at least one first communication antenna and the at least one second communication antenna are provided on the substrate, and the at least one first communication antenna is provided in a position closer to an edge of the substrate than the at least one second communication antenna.

## Claims

### Claim 1

An antenna module, comprising:
a substrate;
at least one first communication antenna by a frequency band belonging to a first frequency range; and
at least one second communication antenna by a frequency band belonging to a second frequency range higher than the first frequency range, wherein
three or more types of antennas by frequency bands different from each other including the at least one first communication antenna and the at least one second communication antenna are provided on the substrate,
the at least one first communication antenna is provided in a position closer to an edge of the substrate than the at least one second communication antenna, and
the second communication antenna by a highest frequency band in the three or more types of antennas in the at least one second communication antenna is provided in a position with a farthest distance from an edge of the substrate.

### Claim 2 (depends on 1)

The antenna module according to claim 1, wherein
the first frequency range is a frequency band equal to or smaller than 2.1 GHz, and
the second frequency range is a frequency band equal to or larger than 5.7 GHz.

### Claim 3 (depends on 1)

The antenna module according to claim 1, wherein
an enclosure which is an obstacle to radio wave is disposed around the substrate.

### Claim 4 (depends on 1)

The antenna module according to claim 1, wherein
a first communication antenna by a lowest frequency band in the at least one first communication antenna is provided in a position with a smallest distance from the edge of the substrate in the at least one first communication antenna and the at least one second communication antenna.

### Claim 5 (depends on 1)

A vehicle roof with an antenna module, comprising:
the antenna module according to claim 1; and
a vehicle roof which is an obstacle to radio wave of at least a part of frequency band, wherein
an opening is formed in the vehicle roof, and
the antenna module is fitted into the opening.

### Claim 6 (depends on 1)

The antenna module according to claim 1, wherein the three or more types of antennas by frequency bands different from each other including the at least one first communication antenna and the at least one second communication antenna are provided on the substrate except for a case where another loop antenna is formed on an inner side of a loop antenna and a patch antenna is formed on an inner side of the another loop antenna.
