The disclosed apparatus may include an antenna radiating structure that includes an active transparent mesh portion as well as a non-transparent antenna radiator portion. By combining transparent metal mesh and non-transparent metallic film into the antenna radiating structure, the disclosed apparatus results in improved radiation efficiency. Moreover, when overlaid on a transparent lens (such as with a pair of augmented reality glasses), the antenna radiating structure leaves the optical transparency of the lens largely unaffected due to the placement of the non-transparent metallic film. Various other implementations are also disclosed.

A radar transmit antenna of a head mounted device transmits a transmission radar signal to a face-region. A radar receiver antenna of the head mounted device receives a return radar signal from the face-region. The return radar signal is matched to a selected expression signal included in a plurality of expression signals stored in an expression database.

A transparent combination antenna is disclosed that provides bandwidth at both sub 6 GHz and the above 24 GHz spectra. For example, the transparent combination antenna can include a first layer of transparent conductive material, and a second layer of transparent conductive material. In some implementations, both of the first layer and the second layer can have different pitches. Additionally, in some implementations, a substrate may be positioned in between the first layer and the second layer. Various other systems are also disclosed.
