ABSTRACT:
A multi-band antenna can be realized by using a common antenna element with a simple configuration. A radio antenna unit includes a ground conductor plate1provided to a casing of a radio device and having a ground potential, a first radio circuit2handling a system in a first frequency band and a second radio circuit3handling a system in a second frequency band lower than the first frequency band, which are provided in the ground conductor plate1, a first feeding line4connected to the first radio circuit2and being a coaxial transmission line having an outer conductor5that is arranged along the ground conductor plate1, an antenna element6connected to the first feeding line4and the outer conductor5respectively, and arranged along the ground conductor plate1, and a second feeding line7for connecting the second radio circuit3and the outer conductor5, wherein the first feeding line4feeds a high frequency power input from the first radio circuit2and the second feeding line7feeds a high frequency power input from the second radio circuit3.
