Abstract:
A new concept of passive waveguide circuits is presented. It is based on a combination of the standard rectangular waveguide with a metal uniform linear polarization grid of nano thickness. The grid is deposited on a polymer foil and inserted into the waveguide, allowing it to rotate between
two opposite flanges. The concept is demonstrated on a T-junction with an adjustable ratio of the output powers, and on a variable reflection attenuator. The two circuits were designed, manufactured and tested. The measured characteristics compare well with the computer simulations, and have confirmed the expected behavior of the two circuits.
