| titleOfInvention | Dual band antenna for radio transceiver |
| abstract | The radio transceiver is configured to have a helical antenna and a whip antenna together, the whip antenna can be stored when needed, and each antenna can operate at two independent frequencies. The helical antenna consists of a first helical portion having a first pitch and a second helical portion having a second pitch, and operates in two frequency bands that are independent of each other. When using a choke structure, the whip antenna surrounds only a conductive inner conductor, a part of the inner conductor (lower portion or the first portion), and the inner conductor filling the gap between the inner conductor and the outer conductor while chopping. It consists of an insulator extending by a certain length from the end of the first frequency band has a structure in which only the first portion operates and in the second frequency band the entire inner conductor operates. When the whip antenna is implemented without using any choke structure, the whip antenna is composed of a conductive conductor and an insulator extending around the conductor and extending by a predetermined length from the end of the conductive conductor. The helical antenna portion and the whip antenna portion are supported by the terminal body by a metal fixing portion, wherein the metal fixing portion is connected to one end of the helical wound in a spiral shape, and forms a passage opening up and down inside the wall. So that the whip antenna can be received inside this terminal through this passage and connected to a feed point. |
