PROBLEM TO BE SOLVED: To provide a multifrequency antenna device which allows for suppression of interference between multiple frequencies, while reducing the size and cost of the device. ! SOLUTION: Multiple patch antennas E1-E6, corresponding to respective frequency signals, are arranged on a dielectric substrate 2, each patch antenna E1-E6 transmits and receives a signal of corresponding frequency, and has a frequency band width that is set narrow so that interference with a signal of other frequency is suppressed. Furthermore, the patch antennas E1-E6 transmitting and receiving signals having frequencies close to each other are located remotely from each other, so as to suppress interference, and the patch antennas E1-E6 transmitting and receiving signals having frequencies far from each other are located close to each other in a range where interference of signals is suppressed. !
