This paper presents the design and development of rectangular microstrip patch antenna (MSA) with complimentary split ring resonator (CSRR) loaded ground plane. Microstrip patch antenna with complimentary split ring resonator (MSACSRR) is used for the reduction in size and enhanced bandwidth. The technique is based on etching out square CSRR which is from the centre of the metallic ground plane behind the radiating patch of the antenna. The MSACSRR makes its size compact by 10.04% compared to the size of the conventional microstrip antenna designed for the same frequency. Along with the size reduction the bandwidth is also increased to 29.6% when compared to the conventional MSA. The results are experimentally measured and compared with IE3D simulated results. The measured and simulated results are presented and discussed, which are in good agreement with each other. The proposed antenna is suitable for WLAN applications.
