Abstract: A high-gain dual-band antenna includes a resonator holder holding a resonator, which is formed of a metal sleeve, a metal barrel axially spaced from the metal sleeve at a distance, and a metal wire conductor connected to and spaced from the inside wall of the metal barrel, a inductor shell capped on the resonator holder to protect the resonator, and a signal line inserted through the resonator holder with a tubular braided conducting layer connected to the metal sleeve and a center conductor soldered to the metal barrel.

Abstract: A wide receiving range antenna is disclosed to include a holder base, and a resonator unit connected to one end of the holder base for receiving signal, which the resonator unit having a barrel connected to the holder base, a metal block spaced from the barrel at a predetermined distance and connected to a coaxial cable being inserted through the holder base, and a plurality of resonators axially extended from one side of the metal block opposite to the coaxial cable for receiving signals of different frequencies and transmitting received signals to an electronic device through the coaxial cable.
