碩士 === 國立臺北科技大學 === 電子工程系研究所 === 105 === Five designs for the radial power divider using substrate integrated waveguide (SIW) are presented in this thesis. This structure is simple and easy to design to a multi-way power divider, and has the advantages of small volume, easy integration into machine design, etc. By changing the radial size, design the bandwidth of 8.6 GHz ~ 9.4 GHz, with low insertion loss of eight-way and five-way non-planar, half-planar and full-planar substrate integrated waveguide power divider, eight-way power divider insertion loss is about -9 dB and five-way power divider is about -7 dB. The non-planar radial power divider using substrate integrated waveguide, the port is feed using SMA connect, and the half-planar and the full-plane radial power divider using substrate integrated waveguide, the port portion needs to be converted to microstrip line. Since the full-planar type will cause an asymmetric case, it will be used at 9 GHz close to the target, and all insertion loss parameters are around -9 dB. A commercial simulation tool, HFSS, will be selected to conduct all the required simulations for the examples. All the simulation data will be verified experimentally.
