In this paper, a W-shaped patch antenna is designed, loaded with CSRR metamaterial structure and Frequency Selective Surface (FSS) technique has been utilized to enhance the performance parameters of the antenna for wireless communication systems. The various types of patch antennas are designed and simulated to the optimal dimensions of the structure. The antenna is designed and simulated in HFSS software, and the proposed W-shaped patch antenna is performed at the frequency of 6 GHz. The proposed antenna and the device is fabricated with FR4 as a substrate material. The simulated results of the reflection coefficient, gain of the antenna are at -21.42 dB, 1.28 dBi, which are closed to the measured values. From the different analysis, the proposed antenna characteristics are obtained not up to the mark, so we have consider the metamaterial and FSS techniques to improve the performance parameters like bandwidth and gain. The proposed structure produces the enhancement in gain, bandwidth, reflection coefficient with Complementary Split Ring Resonator(CSRR) metamaterial, which are 5.9 dBi at 5.5 GHz, -27.56 dB at 6 GHz, -12.65 dB at 4 GHz, -21.24 dB at 8 GHz and also good radiation pattern has been achieved. The metamaterial loaded antenna with FSS also given good results, such as return loss are -13.61, -16.42, -35.86 dB at 4.2, 6.2, 8 GHz, and the gain is 7.1 dB at 6.2 GHz. Here, we have analyzed the various aspects of metamaterial loaded antenna with FSS and the overall antenna performance is observed and the results are obtained as multi bands at 4 GHz, 6 GHz and 8 GHz frequency. The proposed structure is applicable for WLAN (4/6.2/8 GHz) and WiMAX (4/5.5/8 GHz) applications.
