PROBLEM TO BE SOLVED: To provide a single-sided radiation circular-polarization slot array antenna used in a radio communication system using a micro wave or millimeter wave.SOLUTION: A single-sided radiation circular-polarization slot array antenna has a configuration in which: among circular-polarization slot antennas 111, 112, 113 and 114, the antennas 113 and 114 are rotated and arranged by 180 degrees relative to the antennas 111 and 112; coplanar lines 121, 122, 123 and 124 have the same length, and the length is adjusted so that the difference between the length of the coplanar line 126 and the length of the coplanar line 127 is a half wavelength; and a floating metal 102 with the same size as a floating metal 101 is arranged on the back of the antenna.SELECTED DRAWING: Figure 1 |
