This research provides a comprehensive investigation of a Coplanar Waveguide-fed antenna with a secondary parasitic patch for diverse multiband wireless applications. The proposed design consists of four sequential phases that emphasize operational frequency reduction while maintaining a constant overall size. The structure proposed is modelled on a flame retardant (FR4) substrate with an optimised compact dimension of 35 mm × 25 mm. The radiating structure is a simple rectangular patch; a parasitic element is added above it, and changes in ground lead to an improvement in the impedance bandwidth. The proposed configuration resonates for triband; the lower band resonance is tuned by optimizing the slot in the parasitic element; Mutual coupling of the radiating patch and parasitic elements generates the second resonance; and the final resonance is due to a strip in the parasitic patch. This antenna operates at tri-band frequencies (2.45, 3.5, and 5.7 GHz) with fractional bandwidths of 10.5%, 41.7%, and 15.9%, and it can be used for sub-6 GHz 5G, 3.5/5.5 GHz WiMAX, and 2.4/5.2/5.5 GHz WLAN applications, respectively. The antenna has been fabricated, and the prototype's reflection coefficient has been validated with simulated results. The structure also offers positive gain, good impedance, and efficiency above 85% over operating frequencies..
