A conducting thin film and preparation method therefor, a touch panel, and a display device are provided by the present disclosure. The conducting thin film includes a substrate, a conducting layer arranged on the substrate, a protecting layer arranged on the conducting layer, and an electricity conducting adhesive. The conducting layer includes a conducting net formed of conducting material. The protecting layer defines a plurality of openings for exposing the conducting material. The electricity conducting adhesive is formed on the protecting layer such that the electricity conducting adhesive passes through the plurality of openings in contact with the conducting material, and is filled in the plurality of openings. The protecting layer formed before the electricity conducting adhesive, thus reducing the problem of the conducting net breaking caused by the exposed conducting material being oxidized and vulmayized, and the thereby improving the conductivity of the conducting thin film.

Conducting thin film and preparation method therefor, touch panel and display device

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.

Dual-polarized duplex antenna and dual-band base station antenna array composed thereof

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.

Low-profile dual-polarization filtering magneto-electric dipole antenna

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.

Dual-band filtering antenna array using filtering antenna elements for mutual coupling suppression

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.
