CHENG-NAN HU has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11005162
    Abstract: An antenna structure includes a first array antenna having a number of first antenna units. The antenna units are arranged along a first direction and a second direction. The first antenna units are monopole antennas. The monopole antennas include a radiating body having a strip portion and a bulb portion. The radiating body generates radiation along the first direction or the second direction. The strip portion is electrically coupled to a signal source. The bulb portion is electrically coupled to the strip portion. An end of the bulb portion away from the strip portion is semi-circular in shape.
    Type: Grant

  • Publication number: 20210048501
    Abstract: A transmitting device and a receiving device, which can carry out measurements, are disclosed together with a method for estimating an angle of departure of radio waves. The receiving device sets an equal phase of each antenna in a uniform circular array antenna, receives a transmitted millimeter wave signal, and calculates angle of arrival (AOD) of the millimeter wave signal, thus simplifying the steps for estimating AOD.

  • Patent number: 10116064
    Abstract: A millimeter-wave antenna device and a millimeter-wave antenna array device thereof are characterized in that bump portions on coaxial cable connector bases protrude into through holes of a millimeter-wave substrate to effectuate fixation thereof and ensure that the millimeter-wave substrate is tightly coupled to the coaxial cable connector bases to not only ensure the precision of the position of a feed impedance unit of a microstrip antenna structure but also ensure that, when fixed to an antenna back panel frame, a triangular configuration is effectuated such that larger antenna spacing (i.e., 8.5˜12 mm) is achieved while meeting the functional requirement of an antenna beam scan, that is, an allowance of ±30 degrees approximately, thereby circumventing a problem, i.e., the spacing between antenna units is too small to enable an external emitting/receiving module to function.
