b is a side view. FIG. 2 is a characteristic diagram showing its operability, and FIG. 3 shows a double-reflector antenna according to an embodiment of the invention, in which a is a front view and b is a side view. FIG. 4 is a characteristic diagram showing an example of its operating characteristics. In the figure, 1 is the primary radiator, 2 is the sub-reflector, 3 is the main reflector, 4 is the support column, and 5
is a tracking error detection circuit. Note that the same reference numerals in the figures indicate the same pages or corresponding parts.

Claims

[Scope of utility model registration request]
