Design for Tapered transitions From Microstrip Lines to Substrat Integated Waveguide at Ka Ban
In this paper, The concept of substrate integrated waveguide (SIW) technology is used to design filter for 30 GHz communication systems. SIW is created in the substrate of RT/Duroid 5880 having relative permittivity Er= 2.2 and loss tangentQ = 0.0009. Four Via are placed on the century filter the structures of SIW are modeled using and have been optimized in software HFSS (High Frequency Structure Simulator), transition is designed for a Ka-band transceiver module with a 28.5GHz center frequency, . and then the results are verified using another simulation CST Microwave Studio (Computer Simulation Technology). The return loss are less than -18 dB, and -13 dB respectively. The insertion loss is divided equally -1.2 dB and -1.4 respectively.
Keywords: Keywords: Transition, Microstrip, Substrat Integrated Wave guide, Filter,Via.
