Reduced mass printed Quasi-Yagi antennas

摘要

A broadband Quasi-Yagi antenna with 50% mass reduction is proposed and demonstrated. Dielectric material is removed from a conventional printed Quasi-Yagi antenna between the reflector and dipole arms. Additional material is removed around the dipole arms and parasitic director element. Compared to a conventional design, antenna gain is 0.7 dB lower on average over the 3-3.5 GHz operating band. The -10 dB impedance bandwidth is reduced by 收起
