<p>PROBLEM TO BE SOLVED: To provide an antenna, and the like, that can be made compact while suppressing the effects of transmission and reception, of radio waves in one frequency band, on the directivity, and the like, in the transmission and reception of radio waves in other frequency band, in the transmission and reception of radio waves in a plurality of frequency bands.SOLUTION: An antenna unit 110 includes a low frequency antenna provided on the surface of a low frequency reflector 150 and transmitting and receiving the radio waves of low frequency band, and a high frequency antenna for transmitting and receiving the radio waves of high frequency band. Conductors are provided, respectively, from two elements of the high frequency antenna toward the reflector, and the interval in a direction parallel with the low frequency reflector 150 is wider on the side closer to the low frequency reflector 150 compared with the interval on the remote side.</p> |
