Patent number: 9312612Abstract: A variable impedance interface device connecting a coaxial connector to an external component with a housing having a first end adapted to receive a coaxial connector and a second end having an interface where the housing is attachable to an external component, such as a printed circuit board. A cavity within the housing is defined by an inner surface and has a cavity first end and a cavity second end. The inner surface tapers between the cavity first end and the cavity second end. A mating position in the cavity has a certain dimension due to the taper of the inner surface, and defines a location at which a coaxial connector received by the housing positions. An impedance of the housing is based on the mating position and may be varied due to the impedance of the interface such that signal degradation at the interface is reduced.Type: GrantFiled: November 3, 2014Date of Patent: April 12, 2016Assignee: Corning Optical Communications RF LLCInventors: Eric James Paulus, Jeevan Kumar Vemagiri

Patent number: 9179548Abstract: Controlled-impedance out-of-substrate package structures employing electrical devices and related assemblies, components, and methods are disclosed. An out-of-substrate package structure may be used to electrically couple an electrical device to an electrical substrate, for example a printed circuit board. The out-of-substrate package structure may be electrically coupled to the electrical substrate. Ground paths of the out-of-substrate package structure may be arranged proximate to the electrical device and arranged symmetric with respect to at least one geometric plane intersecting the electrical device. In this regard, electric field lines generated by current flowing into the electrical device tend to terminate at the return or ground paths allowing for impedance to be more easily controlled. Accordingly, the out-of-substrate package structure may be impedance matched in a better way with respect to power provided from the electrical substrate enabling faster electrical device speeds.Type: GrantFiled: March 8, 2013Date of Patent: November 3, 2015Assignee: Corning Cable Systems LLCInventors: Thomas Edmond Flaherty, IV, Gary Richard Trott, Jeevan Kumar Vemagiri

Patent number: 8736452Abstract: A chipless RFID tag system having a transmitter sending an input signal and a tag substrate. An ID generation circuit on the tag relies on microstrip transmission line patterns which are pre-designed to generate a unique code. The ID generating circuit may be designed based upon the transmission line properties, including signal delay, and/or reflection, and/or phase change. The tag may be formed on a flexible substrate having at least one microstrip and the microstrip having a first portion with a first impedance and a second portion with a second impedance different from the first impedance. The tag may further include a microstrip antenna for communication with the transmitter and a receiver system. The tag may also include sensors for detection of desired substances of interest. The system may further include a receiver detecting at least two reflections from an interface of first and second impedances and identifying relative time domain positions of the reflections to one another.Type: GrantFiled: March 13, 2008Date of Patent: May 27, 2014Assignee: Louisiana Tech University Research Foundation; a division of Louisiana Tech University Foundation, Inc.Inventors: Khodadad Varahramyan, Mangilal Agarwal, Sudhir Shrestha, Jeevan Kumar Vemagiri, Aravind Chamarti, Sireesha Ramisetti, Mercyma Dee Balachandran

Publication number: 20130293333Abstract: Discontinuous loop antennas and related components, radio-frequency identification (RFID), tags, systems, and methods are disclosed. A discontinuous loop antenna is an antenna loop structure that includes a discontinuity portion. The discontinuous loop antenna can be coupled to an RFID chip to provide an RFID tag. The discontinuity portion decreases the loop inductance and tag capacitance, thus enabling the discontinuous loop antenna to have significantly larger loop area while still matching the chip impedance, resulting in dramatic increases in near-field sensitivity. Increased near-field sensitivity provides increased power harvesting efficiency during near-field coupling. As one non-limiting example, an RFID tag having a discontinuous loop antenna may achieve significantly more power harvesting from a RF signal than an RFID tag having a continuous loop antenna tuned to the same or similar resonant frequency.Type: ApplicationFiled: March 14, 2013Publication date: November 7, 2013Inventors: Jeevan Kumar Vemagiri, Richard Edward Wagner, Matthew Scott Whiting
