| 摘要 |
The invention relates to the structure and manufacturing method of a helix antenna suitable for use in mobile phones and other radio devices. The helix part of the antenna is made of a resilient material, like stainless spring steel wire, and its lower part is wound into a support coil more dense than the rest of the helix. The antenna includes a connector part through which it is electrically and mechanically connected to a radio device. The upper end of the connector part is formed such that when the helix part is fitted onto it, the support coil will undergo a change of form which generates a spring force that keeps the helix electrically and mechanically connected to the connector part. An elastic protective material is fitted onto the helix, attached by melting to a special joint surface in the connector part. <IMAGE> |
