Design of a Novel Dual-band Microstrip Patch Antenna for WLAN/WiMAX Applications Using Complementary Split Ring Resonators and Partially Defected Ground Structure

摘要

This paper proposes a novel low-profile (single-layer) CSRR-loaded microstrip patch antenna placed on a partially defected ground structure (PDGS). The proposed compact dual-band antenna simultaneously satisfies WLAN (Wireless Local Area Network) and WiMAX (Worldwide Interoperability for Microwave Access) application requirements, providing a significantly wide impedance bandwidth (S_(11) ＜ -10 dB) in the WLAN and upper WiMAX frequency regions. The gain and efficiency of the antenna are also very satisfactory in the two frequency bands of operation.
