This configuration radiates at 2.43GHZ (2.27‐2.55 GHz) and 5.52 GHz (5.14‐5.90 GHz) for 2.4, 5.2 and 5.8GHz WLAN bands adopting IEEE 802.11b, IEEE 802.11e and IEEE 802.11a WLAN standards, respectively. The proposed antenna is designed and simulated using CST Microwave Studio 2012 electromagnetic solver based on Finite Integration Technique. The antenna utilizes an H‐shaped defected ground structure (HSDGS) cell on the ground plane which has a triangular cut on one side for dual-band properties. The effect of different dimensions of HSDGS on return loss is also studied. The condensed size, low cost, ease of fabrication, large bandwidth and excellent radiation parameters in comparison with earlier reported designs are the advantages of the proposed antenna. Further the simulated parameters like gain, bandwidth, VSWR, and return loss are in good conformity with ISM (Industrial Sci...

DUAL BAND COMPACT MICROSTRIP PATCH ANTENNA WITH DEFECTED GROUND STRUCTURE
In this paper, a compact dual band rectangular microstrip patch antenna is proposed with the defects integrated in metallic ground plane. Initially a regular rectangular shape patch antenna is designed which resonates at 5.2 GHz. With the introduction of DGS in the metallic ground plane, the microstrip antenna is found to be resonant at 3.5 GHz and 5.2 GHz simultaneously, suitable for WiMAX and WLAN application. Thus the proposed antenna behaves as a compact as well as dual frequency band operated antenna.
