METAMATERIAL INSPIRED FOUR-BAND ANTENNA FOR WIRELESS APPLICATIONS

摘要

Antennas have evolved rapidly since the advent of the wireless network. With the emergence of many new wireless standards in each generation of wireless networks, multi-band antennas have been developed to combine many standards into one device. In this paper, the authors have designed and studied a four-band patch antenna by CPW feeding for modern wireless communication systems, GPS navigation, Wi-Fi, and satellite communication applications. Simulation results of the antenna show that the antenna radiates at four frequency bands, such as 1.8356 GHz for the GPS standard, 2.9765 GHz, 3.7902 GHz, and 5.3977 GHz frequency bands for WLAN standards IEEE 802.11a and IEEE 802.11b & g, and 3GHz-3.63GHz for the WiMAX standard. The proposed antenna results are carried out by the CST software. The antenna characteristics such as return loss, VSWR, radiation pattern, and 3D polar plots are analyzed.
