Abstract
Abstract An antenna for coupling to a printed circuit board comprises a ferrite rod and an electrically conductive coil having at least one turn extending around the core. The ends of the coil form the antenna's leads and are bent to retain the core therebetween. The coil is also bent to form a protrusion which extends away from the core. The antenna's leads and the protrusion may then be coupled to a printed circuit board to secure the antenna.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
99 words
An antenna having provision for mounting to a printed circuit board having receiving apertures therein, said antenna comprising: a core; an electrically conductive coil having at least one turn extending around said core and having first and second end portions for retaining said core between said first and second end portions, said first and second end portions forming leads for insertion into first and second ones of said receiving apertures, said at least one turn having a portion which is bent to form a protrusion away from said core for insertion into a third one of said receiving apertures.
Claim 2
Dependent Claim
