Abstract: Aspects and embodiments of the present invention provide a system for obtaining, processing and managing data from an implanted sensor. In some embodiments, a patient or other persons can use a flexible antenna to obtain data from the implanted sensor. The flexible antenna includes at least one transmit loop and at least one receive loop. The transmit loop is adapted to propagate energizing signals to the implanted sensor. The receive loop is adapted to detect a response signal from the implanted sensor. The transmit loop includes a capacitor formed by a discontinuous area. The capacitor is adapted to allow the loop to be tuned. The flexible antenna can communicate with a patient device that collects the data from the implanted sensor, creates a data file and transmits the data file to a remote server over a network. A physician or other authorized person may access the remote server using an access device.

Abstract: Antenna systems for use with wireless communication devices such as radiotelephones are provided and include a first antenna configured to be internally mounted within a wireless communicator and a second antenna configured to be mounted external to the wireless communicator. The first antenna is resonant within a frequency band and the second antenna is configured to electrically couple with the first antenna so as to enhance the resonant frequency band of the first antenna. The second antenna may be parasitically coupled with the first antenna or directly connected to the first antenna. Alternatively, the second antenna may be directly connected to a ground plane adjacent to a signal feed of the first antenna.

Abstract: A dual frequency band antenna includes a dielectric substrate having opposite first and second surfaces and a meandering conductive trace disposed on a surface of the dielectric substrate. The meandering conductive trace includes first and second meandering segments that are configured to electrically couple with each other such that the antenna resonates within two separate and distinct frequency bands. At least one of the first and second meandering segments has a portion with an increased width compared with the width of the conductive trace.

Abstract: A multiple frequency band antenna for a communications device, such as a radiotelephone, includes a dielectric substrate having high and low frequency band radiating elements disposed on a surface thereof. The high and low frequency band radiating elements have meandering patterns and are electrically connected to a feed point. Lumped electrical elements are electrically connected in series between the high and low frequency band radiating elements at the feed point to reduce coupling effects between the high and low frequency band radiating elements.

Abstract: A C-shaped dielectric substrate having a folded configuration includes opposite first and second spaced apart portions joined at respective adjacent end portions by a third portion. A continuous trace of conductive material, which serves as a radiating element, is disposed on the outer surfaces of the dielectric substrate first, second and third portions. The portion of the continuous radiating element disposed on the dielectric substrate first portion is configured to electrically couple with the portion of the continuous radiating element disposed on the dielectric substrate second portion such that at least two separate and distinct frequency bands are created.

Abstract: Multiple frequency band antennas are pivotally connected to electronic devices such that coaxial connectors are not required. A dielectric substrate, including a plurality of radiating elements disposed thereon, is pivotally connected to an electronic device housing so as to have a predetermined path of rotation from a first position to a second position. At least one of the radiating elements disposed on the dielectric substrate is maintained in a substantially constant spaced-apart relationship with a conductive element disposed within the housing throughout the predetermined path so as to be capacitively coupled with the conductive element.

Abstract: A radiotelephone antenna system includes a parasitic tuning element disposed on a radiotelephone housing so as to be located adjacent a swivel antenna when the antenna is in a stored position. When in a stored position, the antenna overlies at least a portion of the parasitic tuning element. The parasitic tuning element is coupled to the swivel antenna to tune the swivel antenna to a first frequency band and to match an impedance of the antenna with an impedance of the radiotelephone transceiver. Accordingly, a radiotelephone can operate satisfactorily even when a swivel antenna is in a stored position.
