Spinning directional antenna in centimeter and millimeter wave bands

A system comprising:

• an electromagnetic transmitter;
• a first antenna subassembly in electrical communication with the electromagnetic transmitter;
• an electromagnetic receiver;
• a second antenna subassembly in electrical communication with the electromagnetic receiver, wherein at least one of the first antenna subassembly or the second antenna subassembly is a redirecting rotating mirror arrangement that includes:
• a directional antenna subcomponent having a direction of maximum received or transmitted beam intensity;
• a rotatable mirror that reflects an electromagnetic beam to or from the directional antenna subcomponent, the rotatable mirror inclined at an inclination angle with respect to the direction of maximum received or transmitted beam intensity;
• and
• a motor that rotates the rotatable mirror about the direction of maximum received or transmitted beam intensity such that electromagnetic beam is either received from or transmitted to a range of angles as the rotatable mirror rotates;
• and
• a tube into which the rotatable mirror is positioned, the tube being rotated by the motor, the tube having a slit for passing the electromagnetic beam.
