The study introduces an innovative dual-band microstrip patch antenna that operates across multiple frequency bands. The proposed antenna, with dimensions of (29 × 20 × 1.6) mm3, is positioned on an FR-4 substrate possessing a dielectric constant εr of 4.3 and a loss tangent of 0.002. Copper material with a layer height of 0.035 mm forms both the patches and the ground plane. The antenna accomplishes resonance in two frequency bands: (3.332 GHz) and (6.7 GHz). Specifically, it is well-suited for wireless applications in the WIMAX and X-band realms. The obtained VSWR values of 1.018 and 1.308 at these frequencies confirm an effective impedance match. The directivity diagram and radiation characteristics of the antenna enhance its efficiency by exhibiting radiation patterns that align effectively with the requirements of WIMAX and X-band applications. The proposed antenna has undergone successful manufacturing, verification using a Vector Network Analyzer (VNA), and simulation utilizing CST-MW software version 2021.
