1. A playback device comprising:
a multi-band antenna including:
a substrate,
a primary radiator disposed on the substrate, wherein the primary radiator, when driven, resonates at a first resonant frequency, and
a secondary radiator disposed on the substrate and unconnected to the primary radiator, wherein the primary radiator, when driven, induces a current in the secondary radiator such that the secondary radiator resonates at a second resonant frequency different from the first resonant frequency, wherein the secondary radiator is arranged as a slotted radiator having two parallel arms separated by a slot, and wherein the slot is configured to comprise a loop that is formed within the slot;
at least one audio amplifier;
at least one processor; and
at least one non-transitory computer-readable medium comprising program instructions that are executable by the at least one processor such that the playback device is configured to, while wirelessly receiving audio content from at least one data network via the multi-band antenna, playback the audio content using the at least one audio amplifier.
