Split-Ring Resonator Multi-band Antenna for WLAN/WIMAX/X Standard

In this paper, we discussed split-ring resonator inspired monopole antenna design. The proposed design is fabricated on FR-4 substrate (30 × 26.5 × 0.8 mm3) and also covered the WLAN (5.2 GHz Band), Upper WiMAX (3.5 GHz Band), and X Band (7.5 GHz) application. For these ranges, the respectively achieved bandwidths are 3.56 GHz, 5.19 GHz, 7.5 GHz that covered the WLAN, WIMAX, AND X Band wireless standards, respectively. The proposed antenna shows stable radiation pattern.
