摘要
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 6.39.1 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.
