  • Simplified helical antenna structure for communication equipment
    Patent number: 6518938
    Abstract: A simplified helix antenna structure for communication equipment, the antenna is mounted in an internal insulating sleeve thereof with a spiral coil for receiving and emitting signals, the spiral coil is positioned in the antenna under pressure; the bottom end of the spiral coil is a downwardly extending portion which has a specific length with partial length thereof exposed to the outside of the antenna, and the end of the extending portion is electrically connect with an antenna line of an electric circuit board inside of the communication equipment after assembling of the antenna on the equipment. The elastic contact piece and the internal metallic receiving seat used conventionally can thus be saved, and the structure of the helix antenna can be simplified.
