Abstract :
A novel broadband printed dipole antenna with low cross-polarization is presented. The printed dipole employs a double-layered structure where the E-field component perpendicular to the dipole arms is minimized, thus low cross-polarization is obtained. Measurement results show that the printed dipole antenna achieves a bandwidth up to 50% while reducing the cross-polarization level to less than -30 dB within the frequency band.
