Abstract: A dual-polarized duplex antenna includes a top-layer dielectric substrate; a metal reflective ground plate below the top-layer dielectric substrate; vertically-placed duplex baluns for duplexing operation between the top-layer dielectric substrate and the metal reflective ground plate; and four dipole arms horizontally printed on an upper surface of the top-layer dielectric substrate. Each of the duplex balun includes a vertical dielectric substrate, a balun feedline printed on a front side of the vertical dielectric substrate, and a ground plane with a printed slot line printed on a reverse side of the vertical dielectric substrate. The balun feedline includes a low-pass filter, a high-pass filter and a microstrip feeding structure serving as a connection. The low-pass filter and the high-pass filter are located on two sides of the slot line, and are connected together by the microstrip feeding structure.

Abstract: A filtering antenna element and a dual-band filtering antenna array using filtering antenna elements for mutual coupling suppression have been disclosed. The filtering antenna element comprises a feeding element, a sub-substrate, a sup-substrate and an air gap between the sub-substrate and the sup-substrate. A stacked patch is fabricated on a top surface of the sub-substrate, a driven patch and a ground plane are fabricated on a top surface and a bottom surface of the sub-substrate. An asymmetric E-slot is arranged on the driven patch and a shorting pin is inserted into the sub-substrate for generating radiation nulls in stopbands. The dual-band filtering antenna array is compact and needs no feeding network with an isolation of 35 dB, and is suitable for potential base station applications.

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.

Abstract: A low-profile dual-band filtering patch antenna and its application to LTE MIMO system are disclosed. By using two embedded U-shaped radiating patches and a multi-stub microstrip feed-line, two operating bands and four radiation nulls can been generated and individually controlled, the design is thus very simple and flexible. Based on the proposed low-profile dual-band filtering patch antenna, a MIMO antenna with a very low profile, low mutual coupling and low ECCs has been presented.
