Abstract

Based on two-dimensional electronic bandgap(2-D EBG) structure, both straight and curving waveguide transmission line working at 0.14THz are designed Numerical simulation result shows that the S₁₁ parameter of straight and curving waveguide are -81.5dB and -77dB respectively at 0.14THZ, the S₁₁ parameter is below -27dB through the 20 GHz frequency band, the bandgap has good inhibition to the electromagnetic wave. Based on EBG waveguide, EBG power divider and H-plane horn array antenna are designed. Numerical simulation result shows that the S₂₁ parameter of power divider is -3.2dB at 0.14THz, the maximum directivity of array antenna is 16.2 dBi. The array has small side and back lobe. Both E-plane and H-plane pattern are symmetrical.
