Size Reduction of Microstrip Patch Antenna using Complementary Split Ring Resonator Loaded Ground Plane

摘要

In this paper, a design for miniaturization and bandwidth enhancement of microstrip patch antennas is proposed. The technique is based on etching out two rectangular Complementary Split-Ring Resonators (CSRRs) from the centre of metallic ground plane below the radiating patch of the antenna. The simulation study has been carried out by comparing the antenna without CSRR and with CSRR by varying the length of the CSRRs. The proposed design is cost effective and useful for miniaturization of the patch antennas. These antennas find application in WLAN.
