  • Patent number: 12183997
    Abstract: The present disclosure belongs to the field of radio frequency circuit design, and in particular relates to a M×N millimeter wave and terahertz planar dipole end-fire array antenna. The M×N millimeter wave and terahertz planar dipole end-fire array antenna is composed of M paths of N× end-fire linear array antennas arranged at equal intervals, and the distance d between two adjacent N× end-fire linear array antennas is less than ?, where ? is the wavelength, and both M and N are integers greater than 1. By connecting linear type feed networks of the M paths of N× end-fire linear array antennas to M-path in-phase radio frequency signal transmitter and controlling the distance between two adjacent N× end-fire linear array antennas to be less than the effective wavelength, a higher gain and a higher half-power width can be realized, and the power consumption of the transmitter can be reduced.

  • Patent number: 12012502
    Abstract: The present disclosure is related to the field of polymer processing, and, in particular, to a vinyl-modified nanofiller interfacial compatibilizer and a method for producing a compatibilized polymer blend. Vinyl-modified nanofillers can be used together with an initiator as a compatibilizer for polymer blends. The initiator can initiate a free radical reaction between the chains of the polymers in the blend and the vinyl groups on the surface of the vinyl-modified nanofiller, leading to in situ formation of a co-crosslinked polymer and thus compatibilization of the blend as well as improved tensile strength and modulus thereof. Results of examples showed that vinylsilane grafted onto the surface of the vinyl-modified nanofiller makes it possible for the nanofiller to be used as an effective compatibilizer. The vinyl-modified nanofillers can be used as a compatibilizer for various polymer blends systems.
