| contents | Terahertz couplers based on branch lines and waveguide resonators Ching Li Yu‐Hsiang Cheng Microwave and Optical Technology Letters AbstractThis paper presents two waveguide quadrature hybrids in the WR‐3 band, which are designed to be fabricated by computer numerical control milling process with relaxed branch width requirements. An E‐plane four‐branch directional coupler gives an amplitude imbalance less than 0.8 dB and a phase difference between 88° and 94° from 240 to 324 GHz. Another design is an H‐plane bandpass coupler composed of cavity resonators, showing a bandwidth of 2% near 300 GHz. 10.1002/mop.34021 http://onlinelibrary.wiley.com/termsAndConditions#vor |
