| Abstract: | Theory of substrate integrated waveguide (SIW) slot antenna and methods to design broad side standing-wave array are presented. Firstly, initial slot admittance is obtained using ansoft high frequency structure simulator (HFSS) based on the technical requirements. Then, the Matlab software is utilized to fit the data, and finally the mathematical function between the slot conductance and the slot offset is obtained. This method is used to design a 4-elements standing-wave linear array centered at 15.9 GHz with equal amplitude and phase. The design procedure is validated by simulated VSWR less than 1.88 over the bandwidth of 15.8 GHz ~16 GHz. |
