Figure 1 is a front view of a slot array antenna according to an embodiment of this invention, Figure 2 is a diagram showing an example of the radiation pattern and polarization direction of the slot array antenna, and Figure 3 is a diagram of a conventional slot array antenna. The front view and FIG. 4 are diagrams showing examples of radiation patterns and polarization directions by the slot array antenna. In the figure, 1 is a radiating waveguide having a radiating slot on its wide surface, 2 is a radiating slot for emitting radio waves, 3 is a power supply circuit that exchanges power with the radiating waveguide 1, and 4 is a radiating waveguide. 1 center line, 5a-5
e is the amount of deviation from the center line of the slot arrangement, and 6 is the - of the electromagnetic waves radiated from this slot antenna.
In the radiation pattern at the 3 dB level, 7 is the long axis direction of the radiation pattern 6, and 8 is the polarization direction. It should be noted that the same or corresponding parts in the drawings are designated by the same reference numerals.
