Determination of Feed Point by Surrogate Model Based on Radial Basis Function for Rectangular Microstrip Antennas

Due to the latest developments in communication systems, the technology of many devices developed for wireless communication systems have also changed. Therefore, the designs of antenna with properties that are lightweight, cost-effective, small-sized and a wide operating frequency range are very important to use in the mobile wireless communication systems. However, the use of computer-added antenna analysis techniques that can obtain accurate results in order to design antenna designs quickly and effectively has gained importance. In this study, a surrogate model has been proposed to determine the optimal feed point of rectangular microstrip antennas. Twenty-three antennas with different dimensions and dielectric constant values presented in the literature were used for the creation of the surrogate model. The predicted feeding results by the SM are being compatible with the optimal feed points of the antennas determined in the simulation.
