Due to the integration of different wireless applications at different bands on a single device, multi-band microstrip patch antenna is the best solution keeping the overall size of the device small. In the present work, a metamaterial-inspired antenna is proposed for WiMAX/WLAN applications. Design studies, parametric analysis, simulation results along with measurements for an L-shape slotted ground microstrip patch antenna with CSRR (Complementary Split Ring Resonator) embedded on patch structure operating simultaneously at WiMAX (3.5 GHz) and WLAN (5.8 GHz) are presented. The metamaterial-inspired loading is exploited to create resonance for upper WLAN band while an L-shape slot on the ground plane resonates at the WiMAX band, maintaining the antenna's overall small form-factor. The measured S-parameter and radiation patterns of fabricated prototype show that the proposed design is suitable for emerging WiMAX/WLAN applications.
