An antenna arrangement for a solid-state lamp is disclosed. Embodiments of the invention provide for improved performance by positioning the antenna for radio frequency (RF) control of the lamp non-parallel to the main driver board and/or the LED board. This positioning can provide distance from the main board circuitry and a ground plane for the antenna. An RF daughter card can be used for the antenna and also possibly for other RF components. In some embodiments, the antenna is substantially perpendicular to the main board. In some embodiments, the lamp is dimensioned as a replacement for a standard incandescent bulb, such as an A, BR, or PAR bulb. In some embodiments, an optically transmissive enclosure and/or a base define the interior cavity of the lamp. A plurality of LEDs can be disposed within the optically transmissive enclosure.
