Abstract: A connection module for a lamp, preferably an LED-based filament lamp, having an on-board antenna, a driver for supporting such connection module, and a corresponding lamp having such connection module. Accordingly, a connection module for a lamp having a bulb and a base is suggested, preferably for an LED-based filament lamp, including a first side configured to be received by a driver in the base of the lamp and a second side including an elongate region extending towards the bulb of the lamp. The elongate region has a width smaller than a length of the second side and first side, and an antenna. The antenna is integrated in the connection module on the elongate region.
