Title Design of Substrate Integrated Waveguide Slot Array Antennas
Abstract
In recent years, the substrate integrated waveguide (SIW) has got more and more attention in the field of microwave and millimeter wave. SIW is a kind of new guide wave structure with low insertion loss and high Q value, this thesis presented the investigation of SIW slot antenna array.
In this thesis, firstly ,we introduce some of the basic theory of SIW antenna design. For radiating electromagnetic energy, slots are etched at suitable position on the top-wall of SIW, which results in high efficient performance. Secondly, we deduce the theory about linear polarization slot antenna array,which include extraction of single slot electrical parameters and the procedure of the Elliott iterative algorithm. We also simulate X-band SIW linear polarization slot antenna array, W-band air-filled standard rectangular waveguide slot antenna array, W-band SIW linear polarization slot antenna array. Then, we deduce theory about circular polarization slot antenna array,including comparing several different structures of circular polarized element and analysis of circular polarized element. We also simplify complexity of the synthesis algorithm. Furthermore, the simulation and design of Ku-band and W-band SIW traveling wave circular polarization slot antenna array are also given in this thesis.
