The metamaterial inspired low-cost diamond-shaped fractal antenna (DSFA) based on edge-coupled (EC) parasitic split ring resonator (SRR) for multiband wireless application is presented and investigated in this manuscript. Initially, three iterations of DSFA are designed and found that second iteration reveals the more number of frequency bands as compared to the other iterations. For proper impedance matching characteristics, partial ground plane has been introduced in the designing of antenna and low-cost FR4 glass epoxy substrate with thickness of 1.6 mm is used with an overall size of 32 × 36 mm 2 . Further, the EC parasitic SRR is loaded in the geometry of the proposed antenna and compared with the unloaded antenna and noted that the loaded antenna reports the better results in terms of bandwidth and reflection coefficient. The loaded antenna exhibits the maximum bandwidth of 5.68 GHz (1.67–7.34 GHz) and a maximum gain of 8.63 dB at 2.3 GHz and 9.90 dB at 19.9 GHz. The prototype of the proposed DSFA has been fabricated and tested for the authentication of measured results with the simulated results and found both are in agreement with each other. Proposed DSFA with EC parasitic SRR is best suitable for different wireless applications because of its multiband behaviour.
