Abstract

An M-type antenna device is configured to include M-type antenna elements 1 and 2 having mutually different first and second resonance frequencies, a ground conductor, and a power feeder. The M-type antenna unit 1 includes a transmission conductor 6 , a radiation conductor 3 connected between one end of the transmission conductor 6 and the ground conductor 11 , and a radiation conductor 3 connected between the middle portion of the transmission conductor 6 and the power feeding portion 12 . The conductor 4, the radiation conductor 5 connected between the other end of the transmission conductor 6 and the ground conductor 11, the M-type antenna element 2 is configured to have the transmission conductor 6a, the radiation conductors 3a, 4a, 5a, here, the radiation conductor 4a is connected to the power feeder 12 through the radiation conductor 4. Such an antenna device can obtain a small and lightweight antenna device having multiple resonance frequencies and bidirectional characteristics with a simpler design than before.
