Antenna, particularly a mobile phone antenna, and a method to manufacture the antenna
First Claim
1. An antenna (1) comprising a helix (2), a one-piece upper support part and lower connector part, wherein said upper support part (7) supports the helix and said lower connector part (9) connects to the helix, and a protective material layer surrounding the helix and the support part, wherein the lower connector part (9) surrounds a helix leg part (3) which is bent towards the axis of the helix and extends in the direction of the axis through the connector part (9), the lower end of the support part including a support ring (8) with a diameter larger than the helix, and an electrically conducting means (5) connected to the connector part in order to provide an electrical contact for the antenna.

Abstract
A helical mobile phone antenna with a support part (7), a connector (9) connected to the helix, and a protecting case (6) surrounding the helix and the support part. The support part and the connector part are integrally formed, whereby a weak joint between them is eliminated. The lower end of the connector may have an electrically conducting sleeve (5) and is preferably threaded so the antenna can be mounted. The support part (7) and the connector part (9) are molded into an integral body (5), preferably so that the support part surrounds the threaded part of the helix (2), and that the connector part (4) surrounds with a clearance the leg part (3) of the helix. An electrically conducting cylindrical sleeve (5) is connected to the lower end of the connector part, preferably so that the sleeve is arranged in the injection mold, and is fastened to the connector part during molding. Connecting threads (10) for the antenna are formed in the peripheral surface of the connector part or the sleeve.

15. A method to manufacture an antenna, wherein a one piece connector (9) and support part (7) is connected to a helix (2) and the helix (2) is covered with a protective material, said method comprising the steps of:
-
forming one-piece support and connector part (4) comprising an upper support part and a lower connector part, whereby the support part (7) supports the helix, and the connector part (9) surrounds a helix leg part (3), which is bent towards the axis of the helix and extends in the direction of the axis through the connector part (9), forming a widened section at the lower end of the support part to thereby form a support ring (8) which supports a threaded part of the helix (2), connecting an electrically conducting means (5) to the connector part in order to provide an electrical contact for the antenna, and providing the final appearance of the antenna by forming an elastic protective material layer (6) around the helix and the support part supporting the helix. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
