<p>The invention presented relates to wireless handsfree head worn headset computing devices including a microdisplay device and spatially diverse antenna system. The spatially diverse antenna system provides an effective headset computing device radiation pattern that enables arbitrary user movement and promotes freedom of mobility. Disclosed is a headset computing device (100) including a head worn frame (1000) having a profile relatively low in height with respect to a user's head, the user's head creating an RF shadow region along the headset profile by blocking line-of-sight RF propagation paths, the headset includes two or more antennas (1005a, 1005b) integrated with the headset frame to sufficiently maintained its low profile. Each antenna has a radiation pattern and are collectively arranged to form an omnidirectional radiation pattern, where at least a first radiation pattern provides coverage in the line- of-sight propagation path while the at least second radiation antenna pattern is in the RF shadow region.</p> |
