Contribution to the Realization of Miniature DGS Hybrid Microwave Components based on SIW Technology for Telecommunications Systems

Abstract

The trend for the development of communication systems is moving towards minimized weight, reduced size, multiple functions, increased reliability and low cost. Microwave components such as waveguides, filters, etc. represent a very important part of modern telecommunications systems: satellite embedded systems, telecommunication systems in general, etc. To address this problem and for a smaller footprint, scientists have opted for the development of planar structures. A new technology that represents a very promising solution has emerged, namely substrate integrated waveguides (SIW). SIW technology has developed mainly because it shows several advantages such as low production cost, good quality factor and ease of integration into telecommunication circuits. This thesis work is part of the proposal of novel miniature DGS hybrid microwave components based on SIW technology for telecommunications systems that meet all of these required specifications. The simulation will be completed using powerful simulation software such as CST Microwave studio and HFSS, and the simulated models will be manufactured and measured in order to compare the simulated results with those of measurement.
