摘要：
Based on the classical semi-wavelength electro-anticoupled filter theory, this paper studies and designs an electro-anti-coupled half-wavelength rectangular waveguide band pass filter for terahertz communication system. Simulated results show that the center frequency is 94GHz, the band-width is 3%, and the stop-band attenuation better than 40dB is achieved within the range of 66GHz to 71GHz,the pass-band insertion loss less than 0.1 dB, return loss is greater than 19db in the pass band. The filter's structure is simple so it can be easily made.
