摘要： A radar for a vehicle may include a frame having a waveguide antenna embedded therein and extending in a direction crossing an extension direction of the waveguide antenna, a plated region covering at least a portion of the outer peripheral surface of the frame and formed of a metallic material, and an un-plated region not coated with the metallic material on one surface of the frame, wherein the un-plated region is located to be adjacent to the waveguide antenna. Therefore, the radar for the vehicle can improve the stability of an antenna pattern and a phase.

摘要： A package includes an upper level mounted to a lower level. The upper level includes a stack formed by insulating layers and conductive elements and includes a first conductive track of an antenna. A plastic element rests on the stack. A first cavity is defined in the plastic element. A second conductive track of the antenna is located on a wall of the plastic element (for example, in or adjacent to the first cavity). A second cavity is also defined in the plastic element surrounding the first cavity. A third conductive track of the antenna is located on a wall of the plastic element (for example, in the second cavity). A third cavity is delimited between the upper and lower levels and an integrated circuit chip is mounted within the third cavity and electrically connected to the antenna.

摘要： A slot antenna structure includes a metal trough and two metal plates. The metal trough includes a metal bottom plate, two metal sidewalls erected on two opposite long sides of the metal bottom plate respectively, two metal closing walls erected on two opposite short sides of the metal bottom plate respectively, and an opening formed and surrounded by the metal sidewalls and the metal closing walls. The metal plates are provided on the opening. A slot is formed between the metal plates and extends in a straight line to separate the metal plates. An electrical unit is provided on the metal plates and astride the slot. The metal plates and the metal trough form a resonance chamber in communication with the slot. The depth from the opening to the inner bottom side of the metal trough is generally one eighth of the wavelength of an input signal.

摘要： This application provides a phase shifter and an electrically tunable antenna including the phase shifter, where the phase shifter includes a tuning accessory, and the tuning accessory includes a tuning portion for tuning input impedance of the phase shifter. One additional capacitance or inductance parameter is added in the phase shifter by using the tuning portion, to affect input impedance of a port, to further affect a port standing wave, thereby tuning the port standing wave by using the tuning accessory. In addition, the tuning accessory in this application is a molded part with a fixed structure.
