Thisstudy proposesa low-profile filtering antenna based on a magneto-electric dipole. The antennashowed good out-of-band rejection performance without introducing additional filtering circuits and maintainsa lower profile. The filtering performance of the proposed antenna wasintroduced by three radiation zeros. The one radiation zero at high frequency wasthe intrinsic radiation null of the magneto-electric dipole, and the other two radiation nulls wereobtained by a fork-shaped feed structure extended at both ends. The profile of the proposed antenna wasreduced to 0.035λ₀ using the in-phase reflection characteristics of the metasurface structure. Both simulation and measurement results demonstratedthat the proposed filter antenna showedhigh realized gain in the passband and good out-of-band rejection performance in the rejection band.
