An inverted "U" shape patch antenna has been proposed in this research. It is reconfigurable and operates with millimeter waves. Therefore, it is appropriate for 5G wireless networks. Three separate resistors-100, 500, and 750 ohms-that are integrated into the antenna's radiating element have been used to achieve frequency reconfigurability. The proposed antenna is (5mm x 3.2mm) rectangular patch. In this patch, a rectangular slot is made with dimensions (1mmx2.6mm). The proposed antenna is designed on Rogers RT5880 substrate with dielectric constant εr= 2.2 and loss tangent = 0.0009 and its thickness h=1.6mm. It produces three frequencies: 46.2 GHz, 50 GHz, and 50.8 GHz with return losses: -35dB, -25dB, -27dB and peak gains: 7.22dB, 7.15dB ,6.1dB respectively. The proposed antenna has been simulated using CST electromagnetic simulator.
