CPW-fed to CPS Dipole Antenna of Microstrip Tapered Balun with Triangular Loop Director

A CPW-fed to CPS dipole antenna of triangular loop director by microstrip tapered balunis proposed for dual and wide band operations, in this paper. The proposed antenna is consisted of aCPW-fed to CPS transform, microstrip tapered balun element, CPS dipole driver and triangular loopdirector. A dual and wide bandwidth of the proposed dipole antenna is realized by introducing thetriangular loop director and taper matching element. The operated frequency bandwidth is 1GHz(2.14~3.14 GHz) and 1.9 GHz (4.6~6.5 GHz) to return loss criterion of less than 10 dB. The measuredreturn loss of the proposed antenna showed good results of the dual and wide band operating frequencyand the radiation pattern. The proposed antenna is able to support WLAN wireless communicationsapplications. KCI Citation Count: 3
