Study, Design and Simulation of an Array Antenna for Base Station 5G

Patch array antennas are widely used in various applications, namely, wireless communications networks, satellite telecommunications, radar systems, global positioning systems, and telemedicine applications. The purpose of this article is to design and simulate, using the simulation software ADS (Advanced Design System), so we designed a rectangular 1 patch antenna powered by a microstrip line with notch, the results obtained were transformed to a 2 patches array and then to 4 patches powered first in parallel using a power divider. The objective is to achieve: a high directivity of the antenna with better gain and reduced losses by reflection, we analyzed the results for the three coil arrays (1 patch, 2 patch, and 4 patch coil), found that the 4 patch array provides better results than the 1 and 2 patch array, because they show an increase in directivity and gain with a very large bandwidth.
