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 slot and patch antenna design to support multiple frequency bands. Other embodiments utilize a slot and inverted 'F' antenna (IFA) assembly, hybrid slot antenna assembly, or external slot antenna assembly. A split ring antenna assembly can also be used, where individual segments of the ring antenna can support specific frequency bands. Other embodiments utilize a dielectrically loaded planar inverted 'F' antenna (PIFA) assembly to support various frequency bands.
