The wire antenna may be made of a shape memory alloy, such as nitinol. Examples of RF connectors include U.FL, IPEX, IPAX, IPX, AMC, MHF and UMCC connectors that allow the wire antenna to be removably attached to a printed circuit board (PCB) of a lighting control device and to avoid hardwiring the antenna to the PCB. The device that includes the antenna assembly may be incorporated into a luminaire for wireless control of the luminaire. The lighting control device may be installed within the luminaire, such that the wire antenna is positioned between a light source and a diffuser. A number of such luminaries may be combined to provide an intelligent lighting system. ## Claims ### Claim 1 An antenna assembly comprising: a coaxial cable; a radio frequency (RF) connector connected to a first end of the coaxial cable; and a wire antenna attached to a second end of the coaxial cable, wherein, the wire antenna comprises a shape memory alloy. ### Claim 2 (depends on 1) The antenna assembly of claim 1, wherein the RF connector is selected from the group consisting of a U.FL, IPEX, IPAX, IPX, AMC, MHF and UMCC connector. ### Claim 3 (depends on 1) The antenna assembly of claim 1, wherein the RF connector is a U.FL connector. ### Claim 4 (depends on 1) The antenna assembly of claim 1, wherein the shape memory alloy is nitinol. ### Claim 5 (depends on 1) The antenna assembly of claim 1 further comprising a support component that retains and orients at least one of the coaxial cable and the wire antenna. ### Claim 6 (depends on 1) The antenna assembly of claim 1 further comprising a conducting fastener for connecting the wire antenna to the second end of the coaxial cable. ### Claim 7 (depends on 1) A lighting control module comprising a printed circuit board carrying a wireless transceiver and an antenna assembly according to claim 1, wherein the RF connector is removably attached to the wireless transceiver on the printed circuit board. ### Claim 8 (depends on 7) The lighting control module of claim 7 comprising a plurality of the antenna assemblies. ### Claim 9 A luminaire, comprising: a light source; a diffuser, and a wireless lighting control device coupled to control operation of the light source, the lighting control device including a wireless transceiver and an antenna assembly having a wire antenna coupled to the transceiver, wherein the wire antenna is positioned between the light source and the diffuser. ### Claim 10 (depends on 9) The luminaire of claim 9 further comprising a housing and wherein the wireless lighting control device including the wire antenna are positioned within the housing. ### Claim 11 (depends on 9) The luminaire of claim 9, wherein the light source comprises a light emitting diode (LED) source. ### Claim 12 (depends on 9) The luminaire of claim 9, wherein the wire antenna has a length of 50 to 100 mm. ### Claim 13 (depends on 9) The luminaire of claim 9, wherein the wire antenna comprises a shape memory alloy. ### Claim 14 (depends on 13) The luminaire of claim 13, wherein the shape memory alloy is nitinol. ### Claim 15 (depends on 9) The luminaire of claim 9, wherein the antenna assembly further comprises: a radio frequency (RF) connector connected to a first end of a coaxial cable, wherein: the RF connector provides the coupling to the wireless transceiver, and the wire antenna is attached to a second end of the coaxial cable. ### Claim 16 (depends on 15) The luminaire of claim 15, wherein the RF connector is selected from the group consisting of a U.FL, IPEX, IPAX, IPX, AMC, MHF and UMCC connector. ### Claim 17 (depends on 15) The luminaire of claim 15 further comprising a support component that retains and orients at least one of the coaxial cable and the wire antenna. ### Claim 18 (depends on 15) The luminaire of claim 15 further comprising a conducting fastener for connecting the wire antenna to the second end of the coaxial cable. ### Claim 19 (depends on 15) The luminaire of claim 15, wherein: the wireless lighting control device further comprises a printed circuit board carrying the wireless transceiver, and the RF connector is removably attached to the printed circuit board. ### Claim 20 (depends on 9) A lighting system comprising one or more luminaries according to claim 9.
