A printed circuit board (PCB) 2 mounted antenna comprises a radiating element 1 formed from a single piece of metal which is integrated with support and feed members 11, 12. The radiating element 1 may be stamped or etched from a single piece of metal and may be in the form of a planar inverted F antenna, a meander line or straight monopole or dipole arrangement. The feed and support members 11, 12 may be arranged to form part of the radiating structure, tune the antenna resonant frequency, provide impedance matching to the antenna and/or adjust the bandwidth of the antenna. The support and feed members 11, 12 may be arranged for solder mounting in a hole or on the surface of the circuit board 2. Multiple radiating elements may be employed to cover multiple bandwidths. The radiating element may include a meander line with varying pitch to cover different frequencies. The radiating element 1 may be tuned by the cutting of the said radiating element 1. The antenna may include a dielectric cover or loading members 15, 16. This arrangement provides a compact antenna structure which is readily manufactured and directly attached to a circuit board which may be mounted inside a device requiring an antenna.

PCB mounted antenna

A lighting device, such as a replacement lighting device, comprising a light source (LS), eg LEDs, for producing light along an optical axis (OA) A heat sink (HS) made of a material with an electrical resistivity being less than 001 Ωm, eg a metallic heat sink being a part of the housing, transports heat away from the light source (LS) A Radio Frequency (RF) communication circuit (CC) connected to an an antenna (A) serves to enable RF signal communication, eg to control the device via a remote control Metallic components, including the heat sink (HS), having an extension larger than 1/10 of a wavelength of the RF signal are arranged below a virtual plane (VP) drawn orthogonal to the optical axis (OA) and going through the antenna (A) Hereby a compact device can be obtained, and still a satisfying RF radiation pattern can be obtained The antenna can be a wire antenna or a PCB antenna, eg a PIFA or a IFA type antenna In a special embodiment the antenna is formed on a ring-shaped PCB with a central hole allowing passage of light from the light source Preferably, the antenna is positioned at least 2 mm in front of the heat sink (HS)
