M9-11: MICROWAVES - ELLIPTICAL POLARIZATION

ID Code: M9-11
Purpose: Show properties of an elliptically polarized microwave beam.
Description: A dipole antenna with a spiral shape can produce an elliptically or circularly polarized microwave beam. Any orientation of the receiving antenna yields the same signal, as seen in the photographs below, taken at angles of 0, 45, and 90 degrees respectively with respect to the vertical. (See Demonstration M7-01: MICROWAVES - POLARIZATION for the case of a linearly polarized wave. The elliptically polarized wave will be picked up by the receiving antenna in either vertical or horizontal orientation.
