A wire harness includes plural electric wires provided with a connecting unit at an end portion of the plural electric wires, a first antenna connected to the connecting unit and installed in a wireless terminal, and a second antenna connected to at least one of the plural electric wires. An interval between the first antenna and the second antenna is equal to or longer than 0.3λ.
1. A wire harness comprising:
a first electric wire provided with a connecting unit at a first end portion of the first electric wire, the connecting unit is connected to a wireless terminal, the first electric wire lies outside of the wireless terminal, the first electric wire is provided with a second connecting unit at a second end portion, the second connecting unit is configured to connect to a battery unit;
a second electric wire provided with the connecting unit at an end portion of the second electric wire, and the second electric wire lies outside of the wireless terminal and extends along the first electric wire;
a first antenna connected to the connecting unit and installed in the wireless terminal;
a second antenna disposed on the second electric wire; and
a third antenna disposed on the second electric wire at a position having a distance equal to or longer than 0.3λ from the second antenna in an extending direction of the second electric wire from the second antenna, wherein
an interval between the first antenna and the second antenna is equal to or longer than 0.3λ.
2. The wire harness according to claim 1 , wherein
the third antenna is disposed on an end of the second electric wire opposite to the connecting unit.
3. A wire harness comprising:
a first electric wire provided with a connecting unit at a first end portion of the first electric wire, the connecting unit is connected to a wireless terminal, the first electric wire lies outside of the wireless terminal, the first electric wire is provided with a second connecting unit at a second end portion, the second connecting unit is configured to connect to a battery unit;
a second electric wire provided with the connecting unit at an end portion of the second electric wire, and the second electric wire lies outside of the wireless terminal and extends along the first electric wire;
a first array antenna that is connected to the connecting unit and is installed in the wireless terminal;
a second array antenna disposed on the second electric wire at a distance of equal to or longer than 0.3λ from the first array antenna; and
a plurality of other array antennas disposed on the second electric wire at an interval equal to or longer than 0.3λ from the second array antenna in an extending direction of the second electric wire from the second array antenna.
4. The wire harness according to claim 3 , wherein
one of the plurality of other array antennas is disposed on an end of the second electric wire opposite to the connecting unit.
