PROBLEM TO BE SOLVED: To obtain an equivalent antenna characteristic with a simpler configuration of a phase shifter as compared to the conventional antenna.SOLUTION: In an antenna unit 5 of 5-element double slot array antenna 1, double slot antennas 10a, 10b, 10c, 10d, 10e of identical shape are disposed on an identical straight line L of a planar-shaped antenna substrate. Each distance between the adjacent double slot antennas 10 is a half wavelength of a radio communication wave radiated from the double slot antennas 10. |
