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 simple and compact filtering dielectric resonator antenna comprising: a ground plane, a dielectric substrate defined on the ground plane, a dielectric resonator defined on the dielectric substrate, and a hybrid feeding line, the hybrid feeding line comprises: a microstrip line and a metallic conformal strip, and the microstrip line comprises: a microstrip main branch, a first microstrip stub and a second microstrip stub. In the present invention, a hybrid feeding line is firstly employed to a dielectric resonator antenna. It has been shown that this hybrid feeding line can not only increase the impedance bandwidth of the passband but also can introduce two radiation nulls right near the band edges. Both good filtering and radiating performances are therefore obtained without any extra filtering circuit, giving a very compact structure.

Abstract: The invention discloses shared-aperture dual-band dual-polarized antenna array and communication equipment. The antenna array comprises a first dielectric substrate, a second dielectric substrate, a third dielectric substrate, a fourth dielectric substrate, and a fifth dielectric substrate. The first dielectric substrate, the second dielectric substrate, and the third dielectric substrate constitute a dielectric substrate group. The dielectric substrate group is provided with a low-frequency antenna element and four high-frequency antenna elements. The low-frequency antenna element is loaded with a filtering structure. The low-frequency antenna element and the high-frequency antenna element are fed by coaxial lines. The fourth dielectric substrate and the fifth dielectric substrate form a dual-function metasurface. When the dual-function metasurface is used as an artificial magnetic conductor reflector, the radiation of the low-frequency antenna element is enhanced in a low profile, and when used as a frequency selective surface, the electromagnetic scattering of the low-frequency antenna element in the high-frequency band is suppressed. Compared with the existing solutions, the present invention is more compact, and maintains high cross-band isolation and stable radiation patterns in dual bands.

Abstract: The invention presents a LTCC balun filter using two out-of-phase filtering circuits. The LTCC balun filter is comprised of three half-wavelength resonators and grounds which are located on fourteen metal layers. Vias are utilized to connect different metal parts. The first, fourth, seventh, eleventh and fourteenth metal layers are the ground. The three half-wavelength resonators are on the second, third, fifth, sixth, eighth, ninth, tenth, twelfth and thirteenth metal layers. By adjusting the coupling parts of the three half-wavelength resonators, namely the lengths of the seventh, eighth, ninth, tenth and eleventh layers, as well as the distances between them, the coupling strength between the half-wavelength resonators can be tuned. In addition, the quality factor of the circuit can be improved by tuning the port positions. By using the multi-layer LTCC technology, the present invention has the advantage of compact size, novelty, creativity and practicability.
