| 1. A coil device that is used for the transmission and/or reception of signals, comprising
multiple first coils disposed so as to be spaced from each other, each of the multiple first coils comprising a first conducting
section and a second conducting section,
second coils that are electrically connected with each of the multiple first coils, and
transmission means for transmitting signals to the coil device and/or receiving means for receiving signals from the coil
device,
wherein one end of adjacent first coils are connected with a single conductor of one of the second coils and an other end
of the adjacent first coils are connected with a single conductor of another of the second coils, and
wherein the first conducting section comprises a first conducting part, a second conducting part disposed so as to be spaced
from the first conducting part, and a first condenser that electrically connects the first conducting part and the second
conducting part,
wherein the second conducting section comprises a third conducting part, a fourth conducting part disposed to as to be spaced
from the third conducting part, and a second condenser that electrically connects the third conducting part and the fourth
conducting part, and
wherein the transmission means and/or the reception means is connected in parallel with at least one of the first condensers
of the multiple first coils.
