Square Slot Antenna for Dual Wideband Wireless Communication Systems

Abstract

Abstract A square slot antenna fed by two orthogonal feedlines is designed for dual polarized applications. The presented antenna has not only a dual operating band, but also a very wide bandwidth. The bandwidth is 91% in the first band and 40% in the second one. It can simultaneously serve most of the modern wireless communication applications that operate at 1.8, 1.9, 2.4, 5.2 and 5.8 GHz and require wideband characteristics. The antenna can also produce circular polarization with wideband characteristics.
