CERAMIC DIELECTRIC DUAL BAND HELICAL ANTENNA FIXED TO PORTABLE COMMUNICATION TERMINAL

摘要

PURPOSE: a kind of porcelain Jie two-band helical antenna is fixed to mobile terminals and provides in the helical aerials of characteristic, by increasing the productivity of price reduction, and increases reliability. CONSTITUTION: it includes spiral (12,34), whip (13,43) and leaf spring that a kind of porcelain Jie two-band helical antenna, which is fixed to mobile terminals,. A fixed and processing is formed on helicla flute ceramic dielectric material surface has predetermined diameter to be cylindrical. Spiralization is plating trenches metal such as copper. Screw type penetrates through whip. Whip length is formed with straight line. Therefore, whip can move along its length. The insertion when device of leaf spring supports whip whip to be submerged.
