Abstract A new Lanthanum doped Magnesium ferrite ( MgLaxFe2−X) dielectric materials was found using sol–gel auto composition method with four different composition values(x) varying 0.13, 0.25, 0.32 and 0.45 and sintered in microwave furnace at the temperature of 925 °C. The proposed material was investigated under Vibrating Sample Magnetometer test for analyzing its magnetic property. Scanning Electron Microscopy (SEM) test confirmed that prepared material was nano sized material. The phase and homogenized of the material was analyzed under X-ray Diffraction and the chemical components presented in the material was identified under Energy-Dispersive X-ray Analysis. After various investigation, the proposed materials suitable for micro strip patch antenna to be designed and particularly suits for ISM band. The experimental results show better gain of 7.67 dB, Directivity 7.47 dB, with the resonant frequency of 2.4 GHz which yields return loss of − 12.85 dB compared to other micro strip patch antenna.

1 Introduction In recent years, nano composite materials play the vital role to enhance the radiation performance of the antenna from 2.4 to 14.6 GHz applications [1]. Ferrites being magnetic materials have a wide range of applications for high density data storage system, microwave absorbing material, targeted release of drugs, magnetic resonance imaging etc. M gFe2O4 ferrites are partly inverse spine with its ferromagnetic property, since M g2+ is anti ferromagnetic with diffusible in nature. Therefore, its distribution in the crystal lattice site large depends on the synthesis conditions like pH, precursor and heat treatments [2]. These preparation conditions directly affect the cation distribution which in turn reflects in the physical and chemical properties of ferrites to a greater extent by substitution of different metal ions in its tetrahedral and octahedral sites [3].

A variety of chemical synthesis methods are used for synthesizing and analyze nano particles such as sol–gel, wetchemical, co-precipitation auto-combustion, hydrothermal and reverse micelle [4]. The reverse micelles of high reactive powders have been proved to be an effective method for the creation of ferrites. However, it carries out the calcinations at high temperature to obtain the final product of powder with expected crystal structure production of ultrafine particles and good
