1. An antenna comprising:
- a radiating element; and
an antenna reflector comprising a reflective face configured to reflect electromagnetic signals radiated from the radiating element, and a heat dissipating face configured to dissipate heat generated by the antenna into free-flowing air, the heat dissipating face facing away from the radiating element, the reflective face of the antenna reflector and the heat dissipating face of the antenna reflector being different faces on the same physical component.

Abstract
On-board heat dissipation can be achieved in radio frequency (RF) modules by integrating a heat sink into the RF module'"'"'s antenna reflector. Said integration achieves a compact and aesthetically pleasing RF module design that reduces the overall footprint of modular active antenna systems (AASs). Embodiment antenna reflectors include portions that are perforated and/or exposed to free flowing air to provide enhanced heat dissipation capability.
