Abstract

In the present study, the suitability of Ni-Co spinel ferrites as dielectric substrate for microstrip patch antenna has been reconnoitered in X-band frequency range. The scrutinized spinel ferrites with chemical composition Ni1- xCoxFe2O4 (x=0.00,0.30,0.60,0.90) were synthesized using Pechini’s sol gel method. For the present study, Ansoft Designer SV2 was used to design and analyze the microstrip patch antenna. Simulation of antenna was done at resonant frequency of 10.02 GHz, which makes this research to find application in military and surveillance. Firstly, the antenna dimensions were calculated using resonant frequency and electromagnetic properties of the compositions. The antenna output parameters such as return loss, bandwidth, VSWR (Voltage Standing Wave Ratio), Smith Chart and radiation pattern were subsequently analyzed by the simulation Based on the analysis, Ni-Co ferrite Ni0.1Co0.9Fe2O4 has come out to be the best alternative out of the studied compositions for its possible usage as efficient dielectric substrate in microstrip patch antenna in 8.2 – 12.4 GHz frequency range.
