Abstract: The present invention discloses a low-profile broadband high-gain filtering antenna. The antenna comprises a radiator, an upper-layer dielectric substrate, a lower-layer dielectric substrate, a microstrip feed-line having open stubs, a ground plane having a plurality of spaced slots, and a metallized via. The radiator generates resonances, provides a broadband and high-gain radiation passband, and meanwhile, adjusting the dimensions of the radiator can adjust the roll-off rate at the upper edge of the passband. The open stub generates a radiation null, and suppresses a resonance in upper band of the antenna. The spaced slot suppresses a resonance in lower band of the antenna. The metallized via connects the microstrip feed-line and the ground plane, generates a radiation null, and improves the roll-off rate at the lower edge of the passband.

Abstract: The invention discloses a dual-polarized filtering magneto-electric dipole antenna, which comprises an upper dielectric substrate and a lower dielectric substrate. The upper surface of the upper dielectric substrate is printed with a radiator structure, and the lower dielectric substrate is printed with a slot coupling feed network; the radiator structure comprises four parasitic patches loaded with symmetrical slots. The parasitic patches are loaded with short-circuit probes, and the slot coupling feed network comprises two orthogonal sets of Y-shaped feeders and cross-shaped slots, and the cross-shaped slots are printed on a metal floor. The new parasitic slot structures on the radiator structure increases the bandwidth while introducing a high roll-off band edge filtering effect, and combined with the slot coupling feed network with filtering function to achieve good band-pass filtering characteristics and hardly introduce additional insertion loss.
