The products were characterized by scanning electron microscopy, X-ray diffraction, and network analyzer. (Mg0.95Co0.05)2(Ti0.95-Sn0.05)O4 (MCTS) has a dielectric constant (ϵr) of ~14.7, a high quality factor (Q×f ) of ~330, 134 GHz, and a temperature coefficient of resonant frequency (τf) of ~ -46 ppm/°C. 0.48 MCTS -0.52CNT has an excellent combination of microwave dielectric properties: ϵr ~ 28.58, Q×f ~ 208027GHz (at 9 GHz), and τf ~ -4.38ppm/°C sinter at 1325°C, and can be utilized in the fabrication of microwave devices. Therefore, a band-pass filter is designed and simulated using the proposed dielectric to study its performance.4enjournal article
