Diseño y simulación de un array de parches lineal en la banda de las microondas

Nowadays the competition for efficient products takes more and more relevance in each of the industry sectors, as for the satellite, aerospace and cellular industry, they require antennas with low weight, cost and ease of installation, this has driven the need to explore the use of printed circuits that operate as transmission lines and radiating elements. We have chosen to propose the design and simulation of a microstrip patch linear array for applications in the microwave band, more specifically at the 3.6 GHz frequency with the intention that it can be used for 5G applications, as this band operates from approximately 3.3 GHz to 3.8 GHz. In this order of ideas, for the implementation of the array we proceeded to calculate the optimal antenna measurements. For this it was necessary to take into account the characteristics of the substrate with which the array is to be made, then the respective procedure was carried out to find the optimal measurements. Once these measurements were obtained, they were simulated in MATLAB to have a theoretical precedent of the antenna behavior, where the three-dimensional radiation pattern is obtained as a basis, the polar one; where the broadside radiation stands out, and the Cartesian one, where the NLPS stands out. Subsequently, for the simulation under real conditions, the specialized antenna software CST-Microwave Studio was used, where the first antenna was assembled, obtaining return losses with an approximate value of -42 dB and a gain of 7 dBi; and finally, it was replicated to obtain an array of 16 antennas. In general terms, it is possible to demonstrate how the use of tools such as microstrip antennas, specialized software is vital for the economic resolution of problems in different industrial sectors.
