“…The purpose of these studies is to examine and analyze parameters that influence the functioning of the MPA, such as the patch's size, patch's shape, substrate's length, substrate's width, substrate's thickness, and substrate's dielectric constant to improve antenna's performance in terms of gain, bandwidth, reflection coefficient, directivity, and efficiency. Recently, researchers have focused on developing new designs of the MPA, including the shape of the radiator element [12] (such as a rectangle, a square, a triangle, a circle, a ring, or a heart [13]), the operating frequency [14], [15] (such as 2.4 GHz, and 5.8 GHz), the polarization (linear [16] or circular [17]), and miniaturization methods (defective ground structure (DGS) [18], defective microstrip structure (DMS) [19], and electromagnetic bandwidth structure (EBS) [20]). Some work in the literature where the operating frequency is about 2.45 GHz like [21]- [24], the bandwidth of this work is less than 68.80 MHz.…”
