Abstract
Antenna structures for spatial power-combining devices are disclosed. A spatial power-combining device includes a plurality of amplifier assemblies, and each amplifier assembly includes an amplifier coupled between an input antenna and an output antenna. At least one of the input antenna or the output antenna comprises a nonlinear shape that is configured to propagate a signal along a nonlinear path to or from the amplifier with reduced signal loss. Accordingly, each amplifier may be configured on a corresponding amplifier assembly in a position such that each amplifier is spaced farther apart from other amplifiers in the spatial power-combining device. In this manner, heat generated by the amplifiers may be more evenly dissipated by the spatial power-combining device.
