An integrated heatsink and antenna structure that is suitable for inclusion in small and midsized computing devices. The integrated heatsink and antenna structure may include a plurality of fin components that dissipate thermal energy integrated into a heatsink base and a plurality of radio frequency antenna portions coupled to and surrounded by the fin components. The plurality of radio frequency antenna portions may form a monopole antenna. The heatsink base may operate as a ground reference for each of the plurality of the antenna portions and to improve an omnidirectional pattern of each of the plurality of the antenna portions.
