Abstract: Nanocrystalline spinel mixed ferrites are well known for their sensing application. However, they have not been explored much for microwave applications. The microwave dielectric properties of MnxZn(1−x)Fe2O4 were studied to find their utilization as an antenna substrate for microwave wave applications. The sol–gel method was employed to synthesize these ceramics. The formation of spinel structure and crystalline size were confirmed using X-ray diffraction method. Morphology of the samples was studied using the scanning electron microscopy. Relative permittivity (εr) and quality factor (Q × f) of the samples were measured using LCR spectrometer. Based on the material investigation and microwave antenna theory, patch antennas were fabricated and then their performances were studied using return loss analysis. The patch antenna, fabricated from Mn0.2Zn0.8Fe2O4 ceramics showed excellent performances with relative permittivity of 5.76, Q × f of 442, return loss of −41.2 dB and wide bandwidth of 2 GHz.
