A planar printed dipole antenna with wideband performance is presented in this paper. Beveled offset
feeding structure has been introduced between the dipole arms to achieve a wideband impedance
bandwidth. A wideband integrated balun based on microstrip-to-slotline transition has been employed
to excite the proposed dipole antenna. A prototype of the designed dipole antenna is also fabricated
and measured to validate the effectiveness of the proposed design. The measured results are in good
agreement with the simulation results. The fabricated dipole antenna provides a wide impedance
bandwidth defined by |S11| < −10 dB from 2.65 to 17.5 GHz and a flat gain response. The measured
radiation efficiency of the proposed antenna is around 80% within the effective bandwidth. In contrast
with other printed dipole antennas, the designed dipole antenna has successfully achieved a wider
impedance bandwidth with a compact size. The proposed method is simple in comparison with the
other techniques that have been used for bandwidth enhancement.
