Bandwidth Enhancement of Microstrip Patch Antenna with Octagonal Complementary Split Ring Resonator Array Structure

摘要

This paper presents a novel method for the design and fabrication of two microstrip patch antennas with single and multiple Octagonal Complementary Split Ring Resonator Structure (OCSRR) loaded on the ground plane. Bandwidth enhancement is achieved with the microstrip antenna having multiple OCSRR structure. The microstrip patch antenna with single OCSRR structure on the ground plane was designed with a frequency band of 3.88GHz to 4.09GHz and antenna with multiple OCSRR was designed with a frequency band of 3.66GHz to 3.93GHz. The simulated bandwidth of antenna with single OCSRR structure on the ground plane was 210MHz which got improved to 270MHz at a lower frequency band with multiple Octagonal Complementary Split Ring Resonator Structure structured microstrip patch antenna of same physical size. Both antennas were simulated using CST Microwave Studio and ANSYS HFSS.
