Wireless communication plays a vital role in transmitting information from one point to another. Wireless devices have to be smart, intelligent, compact in size, and cost effective to meet the demand of wireless communication. A multi-layered, Split Ring Resonator (SRR), negative permeability material inspired antenna has been designed, analyzed, fabricated, and measured. The developed antenna resonates at 1.13 GHz, 2.47 GHz, and 2.74 GHz frequencies with gain of 3.73 dBi, 6.18 dBi, 1.35 dBi, and bandwidth of 2.10%, 2.81%, and 2.09%, respectively. The structure utilizes FR4 material as a substrate. The engineered model has applications in navigation, WiFi, and satellite communication applications.
Wireless technology plays a vital role in data transfer. There is an acute need of smart wireless devices which could respond effectively for specific applications. This paper presents a defected ground plane based planar antenna. The presented antenna has the potential to operate at 2.47 GHz, 3.55 GHz, and 5.55 GHz frequencies with gains of 3.88 dBi, 3.87 dBi, and 3.83 dBi having impedance bandwidths of 14.61%, 5.42%, and 5.40% respectively. Flame Retardant 4 (FR4) is employed as a substrate. The agreement between simulated and measured results points out the utilization of the presented structure for Wi-Fi/WiMAX/WLAN applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
