Abstract: A low-profile patch antenna based on artificial magnetic conductors (AMC) is being developed for microwave applications. In this article, we proposed an antenna with a DGS (defective ground structure) structure and an array of AMC to improve the antenna's radiation performance. There is an air gap of 10 mm present between proposed antenna and AMC surface. The proposed models operate at two operating frequencies with S11 values of less than - 10 dB in the 4.20-4.28 and 4.86-5.0 GHz bands, respectively. The antenna achieved a gain of 10.1 dBi at 4.25 GHz and 9.54 dBi at 4.91 GHz, respectively. A significant degree of agreement exists between the antenna's simulated and measured parameters.
