Patent number: 10020561Abstract: A “thin” and cost-effective three-dimensional antenna assembly and methods of use and manufacturing thereof. In one exemplary embodiment, the solution of the present disclosure is particularly adapted for small form-factor portable radio devices, and comprises an antenna (or array of antennas) deposited on a thin preformed flexible or deformable structure using a conductive fluid. The antenna (array) includes one or more antennas each having a radiator and a plurality of contacts. Use of the thin preformed structure allows, among other things, thinner form factors for the host wireless device, and obviates use of a separate molded carrier or other more costly or involved processes (such as laser direct structuring).Type: GrantFiled: September 19, 2014Date of Patent: July 10, 2018Assignee: PULSE FINLAND OYInventors: Esa Kalistaja, Riku Lambacka, Petteri Annamaa

Patent number: 9833802Abstract: A conductive element such as an antenna, for use in electronic devices, including mobile devices such as cellular phones, smartphones, personal digital assistants (PDAs), laptops, and wireless tablets, and methods of, and apparatus for, forming the same. In one exemplary aspect, the present disclosure relates to a conductive antenna formed using deposition of conductive fluids as well as the method and equipment for forming the same. In one embodiment, a complex (3D) conductive trace is formed using two or more different print technologies via creation of different domains within the conductive trace pattern.Type: GrantFiled: June 10, 2015Date of Patent: December 5, 2017Assignee: Pulse Finland OYInventors: Esa Kalistaja, Elli Galla, Dan Kuehler, Winthrop Childers

Patent number: 9780438Abstract: Space- and cost-efficient antenna apparatus and methods of making and using the same. In one embodiment, the antenna is formed using a deposition process, whereby a conductive fluid or other material is deposited directly on one or more interior components of a host device (e.g., cellular phone or tablet computer). The antenna can be formed in a substantially three-dimensional “loop” shape, and obviates several costly and environmentally unfriendly processing steps and materials associated with prior art antenna manufacturing approaches.Type: GrantFiled: March 1, 2013Date of Patent: October 3, 2017Assignee: PULSE ELECTRONICS, INC.Inventors: Dan Kuehler, Bruce Hamilton, Alan Benjamin, Petteri Annamaa, Esa Kalistaja

Patent number: 9325060Abstract: A conductive element such as an antenna, for use in electronic devices, including mobile devices such as cellular phones, smartphones, personal digital assistants (PDAs), laptops, and wireless tablets. In one exemplary aspect, the present disclosure relates to a conductive antenna formed using deposition of conductive fluids as well as the method and equipment for forming the same. In one embodiment, a “thick” antenna element can be formed in one pass of a dispensing head or nozzle, thereby reducing manufacturing cost and increasing manufacturing efficiency.Type: GrantFiled: February 11, 2015Date of Patent: April 26, 2016Assignee: Pulse Finland OYInventors: Esa Kalistaja, Elli Galla, Dan Kuehler, Winthrop Childers

Patent number: 7391378Abstract: A radiating antenna element intended to be used in small-sized radio devices, and a radio device having an antenna element according to the invention. The antenna element is part of the covers of a radio device. The antenna element may be conductive throughout, or it may comprise a dielectric portion and a conductive portion, which constitute a single integral component. The radiating portion of the antenna element is relatively large, e.g. in a foldable phone (20) the antenna element (200) may comprise the whole cover of a foldable part (21) except for the front side. The radiating element is advantageously fed electromagnetically through a feed element. As the radiating element is relatively large and is located on the outer surface of the device, the radiation characteristics of the antenna are good, and the space required by the antenna inside the device is relatively small.Type: GrantFiled: January 7, 2004Date of Patent: June 24, 2008Assignees: Filtronic LK Oy, LK Products Oy, Pulse Finland OyInventors: Jyrki Mikkola, Petteri Annamaa, Esa Kalistaja
