  • Publication number: 20240145895
    Abstract: Disclosed is a circular filter assembly, relating to the field of wireless communication. The circular filter assembly includes: a dielectric filter and a dielectric waveguide circulator. The dielectric waveguide circulator is provided with at least three end portions. An end of the dielectric filter is connected to one of the end portions. A cascade matching window is disposed at a connection between the dielectric filter and the end portion, and the cascade matching window is used for adjusting impedance of the circular filter assembly. The dielectric waveguide circulator and the dielectric filter are integrally formed. By integrally forming the dielectric waveguide circulator and the dielectric filter, connecting members between the dielectric waveguide circulator and the dielectric filter can be reduced. In addition, the cascade matching window is added to perform impedance adjustment, to obtain the same standing wave indicator as a conventional connection using a connector.

  • Patent number: 10511375
    Abstract: An IP camera with a wireless relay function includes a lens, a wireless client interface, a wired client interface, a Wi-Fi SoftAP interface, and a bridge interface. The lens receives image data. The wireless client interface transmits the image data to a first wireless client device through a wireless network. The wired client interface transmits the image data to a first wired client device through a wired network. The Wi-Fi SoftAP interface is a virtual interface to be connected to a second wireless client. The bridge interface uses the Wi-Fi SoftAP interface to communicate with the second wireless client, and connects the Wi-Fi SoftAP interface to the wired client interface or the wireless client interface, so that the second wireless client device obtains an IP address and connects to Internet through the wired client interface or the wireless client interface.
