| The design of aperture-coupled reflectarray elements based in Substrate Integrated Waveguide (SIW) technology is presented as an alternative to microstrip delay lines. The element combine the advantages of metallic rectangular waveguides, but with the low cost, low profile and manufacturing advantages of planar technology. In addition, the proposed topology simplifies the multi-stack structure by eliminating one dielectric layer in the design. The inherent shielding provided by the SIW cancels undesirable back radiation, which is difficult to control in the microstrip counterpart. An improved bandwidth for the element is presented by increasing the number of resonant elements, and at the same time optimizing the coupling between all the components of the element. This optimization can also be used to implement sharp frequency selectivity of the reflecting element. Finally, the proposed radiating element can be also used for dynamically control the phase when the waveguide is loaded with a varactor diode. | |
