Antenna adapter
First Claim
1. An apparatus for interfacing a radiotelephone with external equipment, the radiotelephone having an external ground and an antenna removably coupled to an antenna port, the apparatus comprising:
- an electrically conductive elongated member having first and second ends, said elongated member being sized to receive and mechanically engage the radiotelephone;
a matching circuit board mounted on said elongated member at said first end, said matching circuit board containing electrical components to match an impedance of the port;
a first connector coupled to said matching board to connect to the antenna port when the radiotelephone antenna is removed;
a second connector coupled to said matching circuit board to connect to the external equipment, said electrical components coupling said first and second connectors; and
an electrical contact assembly comprising a plurality of electrically conductive pins for connecting to an electrical battery charging assembly, said electrical contact assembly coupled to said elongated member at said second end, for contacting the external ground of the electrical battery charging assembly when the radiotelephone is mechanically engaged with said elongated member.

Abstract
An antenna adapter for interfacing a portable radiotelephone with external equipment. In a preferred embodiment, a connector assembly includes a first connector portion that inserts directly into the radiotelephone'"'"'s antenna port, replacing the normal antenna assembly. Matching electrical components on a circuit board are used to match the impedance of the antenna port of the portable radiotelephone. A second connector portion typically uses conventional RF connectors to couple the radiotelephone antenna port to external equipment.
