Abstract:
A right-hand circular polarized antenna and associated methods. In one embodiment, a quarter-wave antenna configuration is used within a small form factor portable device (e.g. wristwatch). The antenna comprises a radiator element which operates in as a linear polarized antenna while the device is operating in free space. However, when the device is attached to a user (e.g. at a user's wrist), the antenna utilizes the loading of the user's body tissue in order to suppress unwanted signals (e.g. left hand polarized signals) to permit operation in circular polarized mode (e.g. right hand polarized mode), thereby allowing for increased sensitivity to received circularly polarized signals such as those emanated from global positioning satellites.
