Abstract
A stubby antenna comprising a RF conductive connector stud having opposite ends with the stud including means for mounting the antenna in the mounting hole of a communications device such as a cellular telephone. The stud is press-fitted into a body member with the body member having an opening or compartment formed therein which receives a coilform having a coil radiating element and a center wire. The coil radiating element is comprised of a plurality of first coils and a plurality of second coils with the first plurality of coils having a different pitch than the second plurality of coils. The center wire of the radiating element extends through the coils and through the actual bore formed in the coilform. A sheath encloses the body member with the sheath, body member, conductor stud and radiating element being arranged such that the radiating element is held in compression, ensuring that a good electrical contact is made between the connector stud and the radiating element.
