Publication number: 20130265199Abstract: 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.Type: ApplicationFiled: April 4, 2012Publication date: October 10, 2013Inventors: Kimmo Koskiniemi, Pertti Nissinen

Publication number: 20130249763Abstract: A communication antenna for a thin-film mobile device particularly relates to an antenna arranged on a cover of the mobile device and having an enhanced effect on transmission or reception of signals. The communication antenna connected to a transceiver circuit of the mobile device includes a plastic substrate, a metal layer joining an interface layer coated on the plastic substrate, wherein the metal layer is engraved with a separating loop that may have various shapes and areas such that the separating loop encloses an antenna that may have various shapes and areas, and an insulating protective layer coated on the engraved metal layer so as to cover the metal layer and the separating loop. Thereby, the mobile device has an enhanced effect on transmission or reception of signals and provides prevention of electromagnetic interference (EMI).Type: ApplicationFiled: March 26, 2012Publication date: September 26, 2013Inventor: SEN-KUNG HSU
