US Patent 11626654 Heat dissipating antenna structures

An antenna assembly includes an antenna and a heatsink. The antenna may be configured to support radio communications and generate heat, and may include a forward antenna surface configured to transmit or receive communications signals and a rear antenna surface that is affixed to a substrate. The heatsink structure may be positioned to be within a forward electromagnetic field that is emitted from the forward antenna surface and away from the rear antenna surface. The heatsink structure may be configured to perform a convection operation between the antenna and a fluid to perform thermal dissipation of the heat from the antenna.
