  • Patent number: 11349216
    Abstract: The present invention discloses a sector dual-resonant dipole antenna. Radiation elements of the antenna are two identical sector patches. Two identical rectangular notches can be symmetrically arranged or two identical tuning stubs can be symmetrically loaded on the sector patches at positions deviating from the central axis of the two sector patches. Exciting points are symmetrically arranged on sides of the sector patches close to a central axis. The present invention realizes a wide beamwidth radiation characteristic through a two-dimensional sectorial resonator, and then the notches are arranged or the tuning stubs are loaded at appropriate positions of two arms of the sectorial resonator, and thereby a dual-resonant characteristic can be realized within a working band.

  • Publication number: 20210395185
    Abstract: The present invention provides a new, scalable synthetic method for the preparation of non-racemic 1-cyclopropyl alkyl-1-amines, e.g. (S)-1-cyclopropyl ethyl-1-amine. The method makes use of inexpensive starting materials (such as cyclopropyl methyl ketone and S-(?)-?-phenylethylamine) and is well suited for a large scale, industrial process.
