N2 - A novel two-dimensional (2D) square lattice Electromagnetic Bandgap (EBG) structure, including EBG waveguide transmission line, quarter turn, and power-divider, operated at the center frequency of 0.5THz is proposed. Finite element method (FEM) was used to analyze and simulate the EBG structure and these components based on EBG. These components were also compared with traditional ones. Simulation and analysis results show that when the radius of Si-wire satisfied the condition: R=0.4a, where a is the lattice constant, the insertion loss and voltage standing wave ratio (VSWR) of EBG waveguide transmission line and quarter turn are less than -0.05 dB/mm and 1.1, respectively. Meanwhile, the asymmetric division ratio of power divider is better than 0.1 dB. The square lattice has unique advantages in the waveguide transmission line design. The 2D EBG structure can be achieved by using poly-silicon based on MEMS technology with benefits of low loss, planar structures, and high processing accuracy. In addition, it is also easy to integrate with other devices and circuits, such as antennas, filters, diodes, mixers and so on. Hence, this novel EBG structure should have many applications for THz passive components, feed system of antenna array, and integration with other MMIC devices.
