Dual Wideband Stacked Patch Antenna for WiMax and WLAN Applications

Abstract

This paper presents dual wideband microstrip antenna which is designed using stacking configuration to give a better bandwidth as compared to single layer substrate design. The designed slotted stacked patch antenna can operate in the Wimax, (2.2-3.4 GHz) WLAN (2.40--2.48GHz), and UMTS II (2.50--2.69GHz) frequency band giving a maximum bandwidth of 37.95%. The air is used as a dielectric between the two stacks and a height of 10 mm is kept between the two stacks. The feeding technique used in the design is the coaxial probe feed and the impedance matching and radiation characteristics of the structure are investigated using MOM based IE3D. The simulation result shows that the proposed antenna can offer excellent performance for Wi Max and WLAN application.
