ABSTRACT:
A dual polarized flat plate antenna structure has a single circular waveguide output accommodating probes for separate orthogonally polarized signals. A housing to be affixed to the antenna structure contains a low noise block having a single circular waveguide input with complementary probes. The housing is rotatable relative to the antenna structure about the common axis of the waveguides. The low noise block incorporates switching means for selectively coupling the output signals of the antenna array structure with a common low noise block input circuit. Rotation of the low noise block enables the angle of the polarizing coupling between the array output probes and the low noise block input probes to be varied.
