Microstrip antennas, Multilayer substrate, Nickel ferrite, Niobium pentoxide.
Modern mobile communication systems, wireless communication services, IoT (Internet of Things), radio links and satellite communication, radio location, among others, have been increasing in quantity, quality and operating requirements. Among these requirements are increased bandwidth, increased operating frequency and decreased physical dimensions, for example. The microfite antenna is very versatile, has very interesting features, such as thin profile, low weight, small size, easy to manufacture and low cost. The microfite antenna can be constructed with various types of dielectric and / or magnetic materials. The excitation of the antenna can be done by microfita line, coaxial cable, or electromagnetic coupling, bringing much versatility to the antenna. Many papers that the inclusion of magnetic materials in the antenna substrate can play an important role in decreasing the dimensions and increasing the antenna bandwidth. This work proposes to study and analyze the effects of multilayer in the microfite antennas with interlayer substrate of niobium pentoxide (Nb2O5) and nickel ferrite (NiFe2O4) in the frequency of 10GHz. A basic design of a standard antenna with niobium pentoxide substrate will be carried out, which will be simulated, constructed and measured, the same frequency will be applied to an antenna with a nickel ferrite substrate to perform a comparison and analysis of the effects of substrate change and its magnetic properties, a multilayer with niobium pentoxide substrate, nickel ferrite and niobium pentoxide will be produced, and an effect and behavior of the microfill antenna over multilayer will be performed.
