Substrate Integrated Waveguide-Oriented Design Applied to the Antenna Section of mm-W Communication Systems: Challenges and Advantages

This paper addresses a number of technological and theoretical aspects of employing the Substrate Integrated Waveguide (SIW) technology in the design and implementation of the antenna section of different communication systems operating at millimeter-wave (mm-W) frequencies. An SIW-oriented design presents a number of immediate advantages, such as a massive reduction in system complexity, antenna isolation enhancement, and low-cost implementation. Moreover, the SIW technology permits to adopt a number of antenna topologies featuring several advantages in terms of reconfigurability and dynamic performance, which becomes extremely beneficial in the synthesis of modern phased array configurations.
