Abstract

Analysis of a W-band meander-line slow-wave structure has been carried out using quasi-TEM approach and validated against CST-Microwave studio for the dispersion and interaction impedance characteristics. A waveguide coupler is designed using HFSS and large signal analysis is carried out for output power and gain. A cold test model of the structure is fabricated at Ku-band frequency and cold test measurement is carried out for the dispersion characteristics and results are compared against analysis results.
