Novel low‐ ε r , thermal and phase stable of (1‐x)Mg 3 B 2 O 6 ‐xBa 3 (VO 4 ) 2 (x mol% =51, 53, 55, 57, 59) microwave composite ceramics were firstly fabricated and reported using the conventional solid‐state reaction method. X‐ray diffraction, scanning electron microscopy, energy dispersive X‐ray, and Raman spectroscopy confirmed the coexistence of both phases without other phases. Near‐zero temperature coefficient of resonant frequency ( τ f ~ +1.2 ppm/°C) is obtained for the 0.43Mg 3 B 2 O 6 ‐0.57Ba 3 (VO 4 ) 2 composite ceramic, with permittivity ( ε r ) of 8.8 and high‐quality factor ( Q × f ) of 45 420 GHz, which is a promising candidate for 5G applications.
