Abstract

The wireless LAN (WLAN) revolution is about to sweep the globe. WLAN access points are being set up all over the world. The need to design an antenna with greater efficiency and wider bandwidth is essential for high-speed wireless data transfer. This paper describes the numerical study of microstrip-coupled rectangular DRA (RDRA) using a commercial E.M. simulator. The RDRA is positioned on top of an open-end microstrip feed line and hence coupled to the microstrip line electromagnetically. The dominant TE₁₁₁^y mode is excited in the frequency range of 2.20-2.95 GHz. The study includes several substrate configurations. The results on the effect of the position of RDRA with respect to the strip line and substrate parameters on the frequency and impedance bandwidth are reported.
