Dual band aperture coupled microstrip patch antenna using different aperture shape for wireless LAN application
description A wireless Local Area Network (WLAN) application nowadays has become more popular. Since it allows users to access network services without being tethered to a wired infrastructure. Point to point and point to multipoint communication brings a crucial responsibility to antennas since they are expected to provide the wireless transmission between those devices. In high performance point to point and point to multipoint application where size, weight, cost, performance, ease of installation are constraints, low profile antenna is very much required. To meet these requirements, microstrip antenna preferred. Microstrip antenna is currently one of the fastest growing segments in the telecommunications industry and promise to become the preferred medium of telecommunications in the future. Although microstrip antenna has several advantages, it also has several disadvantages such as low gain and narrow bandwidth. These disadvantages can however be overcome by constructing many patch antennas in array configuration. With the modern increase in the use of microwave frequencies in communication and radar applications, certain antenna performance requirements are needed and should be an integral part of the design process. For example, GPS (Global Positioning System), WLAN (Wireless Local area network) are all applications that share a common requirement in their antennas. They all require an antenna that is small in size and volume, low in cost and weight, easy to design, and can perform efficiently at two distinct frequencies that may be separated far apart. Two Dual band aperture coupled microstrip antennas using elliptical and triangular aperture shape operating at 2.45 GHz and 5.8 GHz was designed, fabricated and tested. These designs were simulated with Computer Simulation Technology and tested with Hand Held Spectrum Analyzer. Both, simulated and measured data were compared and contrasted.
