Abstract
An antenna system for a wearable device comprises an antenna that includes a plurality of elements. The elements include an antenna element that comprises an electrically conductive material. The antenna also includes one or more feed points configured for operable coupling to a wireless transceiver. Additionally, the antenna includes a set of one or more switch units. For each respective switch unit of the set of switch units: the respective switch unit is connected to one or more elements of the respective switch unit in the plurality of elements, a flow of electrical current to the one or more elements connected to the respective switch unit is dependent on a switch state of the respective switch unit. A radiation characteristic of the antenna is dependent on the switch states of the switch units.
