The RF antenna module includes an antenna element disposed in or on a remote housing and further includes an RF coaxial cable having one end in electrical communication with the antenna element and an opposite end in communication with the wireless transceiver module. Improved transmission and reception performance are achieved through increased separation of the antenna module from a user's head and body as compared to an antenna element disposed in the earphone. In addition, the size of the earphone can be reduced relative to an earphone having an antenna element. ## Claims ### Claim 1 A personal acoustic device comprising: an earphone having an acoustic transducer; a wireless transceiver module disposed in the earphone; and a radio frequency (RF) antenna module in electrical communication with the wireless transceiver module, the RF antenna module comprising: an antenna element disposed at a housing that is remote to the earphone; and an RF coaxial conductor having a first end in electrical communication with the antenna element and a second end in electrical communication with the wireless transceiver module, wherein the RF antenna module is configured to receive a wireless signal incident at the antenna element and the RF coaxial conductor, and wherein the RF antenna module is configured to transmit a wireless signal from the antenna element and the RF coaxial conductor. ### Claim 2 (depends on 1) The personal acoustic device of claim 1 further comprising the housing with a user interface module disposed therein, the housing being disposed at the first end of the RF coaxial conductor. ### Claim 3 (depends on 2) The personal acoustic device of claim 2 wherein the antenna element is disposed inside the housing. ### Claim 4 (depends on 2) The personal acoustic device of claim 2 wherein the antenna element is disposed on a surface of the housing. ### Claim 5 (depends on 1) The personal acoustic device of claim 1 wherein the antenna element is a monopole antenna. ### Claim 6 (depends on 1) The personal acoustic device of claim 1 wherein the antenna element is a loop antenna. ### Claim 7 (depends on 1) The personal acoustic device of claim 1 wherein the antenna element is formed on a printed circuit board. ### Claim 8 (depends on 7) The personal acoustic device of claim 7 wherein the printed circuit board is a flexible printed circuit board. ### Claim 9 (depends on 1) The personal acoustic device of claim 1 wherein the earphone comprises an earbud configured for insertion into an ear canal of a user. ### Claim 10 (depends on 1) The personal acoustic device of claim 1 wherein the wireless transceiver module is a Bluetooth transceiver module. ### Claim 11 (depends on 2) The personal acoustic device of claim 2 further comprising a cable extending between the housing and the earphone, the cable having a jacket enclosing at least one electrical conductor and the RF coaxial conductor. ### Claim 12 (depends on 11) The personal acoustic device of claim 11 wherein the at least one electrical conductor includes at least one of a power conductor, a ground conductor, a microphone coaxial conductor and a twisted pair conductor. ### Claim 13 A personal acoustic system comprising: an earphone having an acoustic transducer; a wireless transceiver module disposed in the earphone; a radio frequency (RF) antenna module in electrical communication with the wireless transceiver module, the RF antenna module comprising: an antenna element disposed at a housing that is remote to the earphone; and an RF coaxial conductor having a first end in electrical communication with the antenna element and a second end in electrical communication with the wireless transceiver module, wherein the RF antenna module is configured to receive a wireless signal incident at the antenna element and the RF coaxial conductor, and wherein the RF antenna module is configured to transmit a wireless signal from the antenna element and the RF coaxial conductor; and an audio source device configured for wireless communication with the wireless transceiver module. ### Claim 14 (depends on 13) The personal acoustic system of claim 13 wherein the audio source is one of a cellular telephone, smartphone, tablet, personal computer and music playback device. ### Claim 15 (depends on 13) The personal acoustic system of claim 13 further comprising the housing with a user interface module disposed therein, the housing being disposed at the first end of the RF coaxial conductor. ### Claim 16 (depends on 15) The personal acoustic system of claim 15 wherein the antenna element is disposed inside the housing. ### Claim 17 (depends on 15) The personal acoustic system of claim 15 wherein the antenna element is disposed on a surface of the housing. ### Claim 18 (depends on 15) The personal acoustic system of claim 15 further comprising a cable extending between the housing and the earbud, the cable having a jacket enclosing at least one electrical conductor and the RF coaxial conductor.
