1results about How to "Realize Broadband" patented technology

The embodiment of the present application discloses an antenna and a broadband matching network, the broadband matching network comprises: a passive impedance matching circuit and a non-Foster impedance matching circuit. The passive impedance matching circuit has a first port and a second port; the second port is connected with a coaxial port. The non-Foster impedance matching circuit has an input end and an output end; the input end is connected with the first port, and the output end is connected with a feed end of the antenna. The passive impedance matching circuit comprises at least one capacitor and at least one inductor which are connected with each other; and the non-Foster impedance matching circuit comprises at least one transistor and at least one capacitor, inductor or resistor which are connected with each other. The antenna of the embodiment of the present application realizes impedance matching between a coaxial cable and the feed end of the antenna by using the broadband matching network, realizes the broadband design of the antenna, and provides convenience for the miniaturization of the antenna.
