I am pleased to invite you to Harold Theiba's presentation on the Global 3DEXPERIENCE Modeling and Simulation Virtual Conference on November 17th & 18th.

Abstract

A study carried out to investigate how a 4x4 patch antenna array operating at GHz frequencies can be designed and how its different configurations affect beam direction, shape, and width is presented in this dissertation. In this experiment a 4x4 antenna array was designed using two FR-4 substrates separated by a copper ground plane. The patch antennas sat on the top substrate and were connected to a corporate feed network on the bottom substrate by probes. The feed network was designed to ensure each patch is excited simultaneously so that they are equal in phase and amplitude, in order to produce a very directive signal (pencil beam). A second design using coaxial feeding for each patch was also created to run simulations for different configurations of the antenna array. An antenna CAD software, CST Studio Suite 2019, was used to design the arrays and run their simulations. The simulated gain (IEEE) of the complete antenna array and its directivity were 18.51 dBi and 18.71 dBi respectively. Its return loss was -37dB with a bandwidth of 101 MHz and a half power beam width.
