Abstract
Various antenna designs are presented that can be used to provide for wireless communication in electronic devices, such as wearable electronic devices. Various embodiments provide antenna structures and designs that can support multiple frequency bands in a relatively compact space. Various embodiments utilize a ring antenna forming a portion of an outer perimeter of the housing, the ring antenna including a plurality of connections coupled the PCB, the plurality of connections. The plurality of connections include at least one feed connection coupled to at least one signal source on the PCB, respectively, and at least one ground connection coupled to a ground point on the PCB. In some embodiments, the connections may be inductively or capacitively loaded. The ring antenna may include a single feed connection or multiple feed connections respectively coupled to different signal sources.
