A broadband double‐layered printed dipole antenna with parasitic strips is presented.The printed dipole uses a double‐layered structure and is fed by an integrated strip‐line balun. Two pairs of parasitic strips are attached around the dipole to expand the impendence and pattern bandwidth. Measurement results show that the proposed antenna achieves 75% impendence bandwidth (VSWR < 2), operating between 2.5 and 5.5 GHz. Moreover, stable radiation patterns with 6.3–9.1 dBi peak gain and low cross‐polarization are obtained within the bandwidth. An eight‐element printed dipole antenna array is assembled and measured, showing a good performance in the array. © 2012 Wiley Periodicals, Inc.
