摘要： 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.

摘要： Described herein are systems, methods and devices for implementing a temperature-aware, multi-antenna scheduler that cools mmWave devices by preventing heat buildup via switching or distributing a data stream to other redundant antennas, allowing for dissipation of heat as well as providing reliable connectivity.

摘要： A reconfigurable antenna apparatus may include an antenna assembly and control circuitry. The antenna assembly may include an antenna patch array having a plurality of antenna patches and a switch array having plurality of switches. Each switch of the plurality switches may be electronically controllable to transition between states including a conducting state and a non-conducting state. Each switch may be electrically connected between two of the antenna patches of the antenna array. The control circuitry may be configured to control the states of the switches of the switch array to operate the antenna patch array in a first communications mode at a first wavelength, and control the states of the switches of the switch array to operate the antenna patch array in a second communications mode at a second wavelength.
