20100244978 | METHODS AND APPARATUS FOR MATCHING AN ANTENNA - A method and an arrangement for matching the antenna of a radio device in transmitting condition. The antenna impedance in the output of the power amplifier of a transmitter is adjusted by means of a π-shaped reactive matching circuit, the component values of which can be selected from a relatively wide array of the alternatives. The component values are selected by means of the multiple-way switches, which only are located in the transverse branches of the matching circuit. The switches are set ( | 09-30-2010 |
20100321250 | Antenna, Component and Methods - An antenna component (and antenna) with a dielectric substrate and a plurality of radiating antenna elements on the surface of the substrate. In one embodiment, the plurality comprises two (2) elements, each of them covering one of the opposite heads and part of the upper surface of the device. The upper surface between the elements comprises a slot. The lower edge of one of the antenna elements is galvanically coupled to the antenna feed conductor on a circuit board, and at another point to the ground plane, while the lower edge of the opposite antenna element, or the parasitic element, is galvanically coupled only to the ground plane. The parasitic element obtains its feed through the electromagnetic coupling over the slot, and both elements resonate at the operating frequency. Omni-directionality is also achieved. Losses associated with the substrate are low due to the simple field image in the substrate. | 12-23-2010 |
20110181476 | MINIATURE PATCH ANTENNA AND METHODS - A miniature patch antenna element useful for wireless applications such as portable radio devices, and methods for using and manufacturing the same. In one embodiment, a plurality of discrete ceramic elements creates a spatially loaded miniature patch antenna. Ceramic material is placed only at locations where it achieves the desired effect on reducing the physical length of a half-wave radiator. In one variant, these locations comprise the edges of the half-wave radiator (e.g., metallic plate). This configuration advantageously has lower weight, smaller size and reduced cost that result from using less ceramic material in the construction of the antenna. Moreover, RF performance of the antenna is improved as compared to a fully ceramic construction, as electric field losses in the spatially loaded antenna structure are reduced as well. | 07-28-2011 |

20130265199 | COMPACT POLARIZED ANTENNA AND METHODS - 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. | 10-10-2013 |
20140118196 | MODULAR CELL ANTENNA APPARATUS AND METHODS - Simple, low-cost and modular antenna apparatus and methods associated therewith. In one embodiment, a modular antenna element that can be used either alone or as a basic “building block” for larger arrays and sectorial antennas (i.e., by joining needed number of elements together) is provided. The same parts can be reused for various complete product designs, thereby advantageously reducing the need for customized parts (and the attendant disabilities associated therewith). Moreover, multiple antenna elements can be readily joined together via a common feed network (in one implementation, via the back portion of each element). The antenna gain and beam width are also adjustable through configuration of the array (and the construction of the antenna elements themselves). | 05-01-2014 |

In one exemplary embodiment, the solution of the present disclosure is particularly adapted for small form-factor, metal-encased applications that utilize satellite wireless links (e.g., GPS), and uses an electromagnetic (e.g., capacitive) feeding method that includes one or more separate feed elements that are not galvanically connected to a radiating element of the antenna.
