Patent number: 9484619Abstract: An active diversity antenna apparatus and methods of tuning and utilizing the same. In one embodiment, the active diversity antenna is used within a handheld mobile device (e.g., cellular telephone or smartphone), and enables device operation in several low frequency bands (LBs). The exemplary implementation of the active LB diversity antenna comprises a directly fed radiator portion and a grounded (coupled fed) radiator portion. The directly fed portion is fed via a feed element connected to an antenna feed. The coupled fed portion of the LB antenna is grounded, forming a resonating part of the low frequency band. A gap between the two antenna portions is used to adjust antenna Q-value. Resonant frequency tuning is achieved by changing the length of the grounded element. The LB feed element is disposed proximate the feed element of a high band diversity antenna, thus reducing transmission losses and improving diplexer operation.Type: GrantFiled: December 21, 2011Date of Patent: November 1, 2016Assignee: PULSE FINLAND OYInventors: Heikki Korva, Ari Raappana, Petteri Annamaa

Publication number: 20160276748Abstract: Multi-element antenna apparatus for mobile devices and methods of utilizing the same. In one embodiment, the antenna apparatus includes three antenna elements configured to operate in a plurality of frequency bands. The antenna elements are to a transceiver engine of a radio frequency communications device. Two of the three antenna components are configured to operate in transmit and receive modes. The third antenna component is configured to operate in receive mode. In some embodiments of an antenna apparatus operable in a carrier aggregation communication mode, two antenna components may be electrically combined into a single antenna component. The combined antenna component, characterized by a larger dimension and a larger operating bandwidth, may be operable simultaneously in two frequency bands, thereby enabling the carrier aggregation intra-band communication.Type: ApplicationFiled: March 17, 2015Publication date: September 22, 2016Inventors: Prasadh Ramachandran, Kimmo Koskiniemi, Heikki Korva, Petteri Annamaa

Patent number: 9450291Abstract: A multiband slot loop antenna apparatus, and methods of tuning and utilizing the same. In one embodiment, the antenna configuration is used within a handheld mobile device (e.g., cellular telephone or smartphone). The antenna comprises two radiating structures: a ring or loop structure substantially enveloping an outside perimeter of the device enclosure, and a tuning structure disposed inside the enclosure. The ring structure is grounded to the ground plane of the device so as to create a virtual portion and an operating portion. The tuning structure is spaced from the ground plane, and includes a plurality of radiator branches effecting antenna operation in various frequency bands; e.g., at least one lower frequency band and three upper frequency bands. On one implementation, a second lower frequency band radiator is effected using a reactive matched circuit coupled between a device feed and a radiator branch.Type: GrantFiled: July 25, 2011Date of Patent: September 20, 2016Assignee: PULSE FINLAND OYInventors: Heikki Korva, Petteri Annamaa

Patent number: 9406998Abstract: A distributed multiband antenna intended for radio devices, and methods for designing manufacturing the same. In one embodiment, a planar inverted-F antenna (PIFA) configured to operate in a high-frequency band, and a matched monopole configured to operate in a low-frequency band, are used within a handheld mobile device (e.g., cellular telephone). The two antennas are placed on substantially opposing regions of the portable device. The use of a separate low-frequency antenna element facilitates frequency-specific antenna matching, and therefore improves the overall performance of the multiband antenna. The use of high-band PIFA reduces antenna volume, and enables a smaller device housing structure while also reducing signal losses in the high frequency band. These attributes also advantageously facilitate compliance with specific absorption rate (SAR) tests; e.g., in the immediate proximity of hand and head “phantoms” as mandated under CTIA regulations.Type: GrantFiled: April 21, 2010Date of Patent: August 2, 2016Assignee: Pulse Finland OYInventors: Heikki Korva, Petteri Annamaa, Ari Raappana

Patent number: 9246210Abstract: A monopole antenna applicable especially to small mobile stations. In one embodiment, the radiator of the antenna is trough-like in shape so that it covers the head surface, front and rear surfaces and both side surfaces of the dielectric cover of the radio device at an end of the device. On the side of the side surfaces slots are formed in the radiator, starting from its edge, for increasing the electric size. The radiator is fed electromagnetically by a separate element which is shaped so that the antenna has at least two operating bands. The ground plane of the antenna is in one embodiment disposed apart from the radiator, thus not extending inside the ‘trough’.Type: GrantFiled: February 7, 2011Date of Patent: January 26, 2016Assignee: PULSE FINLAND OYInventor: Heikki Korva

Patent number: 9203154Abstract: An internal dual band antenna meant for small radio devices. In one embodiment, the antenna contains two radiators and a parasite element, which is shared between them. The parasite element is implemented on three sides of the antenna module, which are perpendicular to the side where the two radiators are implemented. The short-circuit conductor of the parasite element extends close to the supply point/points of the antenna on the circuit board of the radio device and is connected to the ground plane of the radio device. The antenna structure is dimensioned such that the two resonance frequencies on both functional bands are at a lower frequency than the resonance frequencies of the actual radiators. Accordingly, both the lower and upper frequency band is widened. The shape of the parasite element does not weaken the adaptation of the antenna in either functional band.Type: GrantFiled: January 12, 2012Date of Patent: December 1, 2015Assignee: Pulse Finland OyInventor: Heikki Korva

Patent number: 8847833Abstract: A radiating antenna element intended for portable radio devices and methods for designing manufacturing the same. In one embodiment, a loop resonator structure for enhanced field (e.g., electric field) is provided, the resonator having an inductive and a capacitive element forming a resonance in a first frequency band. The loop resonator structure is disposed substantially on the ground plane, thereby altering electrical energy distribution. The location of the resonant element is selected to reduce electric field strength proximate to one or more sensitive components, such as a mobile device earpiece, thereby improve hearing aid compliance. Capacitive tuning of the resonator, and the use of multiple resonator structures on the same device, are further described.Type: GrantFiled: December 29, 2009Date of Patent: September 30, 2014Assignee: Pulse Finland OyInventors: Heikki Korva, Petteri Annamaa

Publication number: 20130194150Abstract: An antenna of a laptop device, which can be connected wirelessly to a communication network. The apparent size of the antenna's ground plane (GND), as ‘seen’ from the feed of the monopole radiator (410), is reduced so that the outer peak of the strength of the electric field in the near field of the ground plane falls about at the distance of a quarter wavelength from the outer end of the radiator at the frequencies in the lower operating band of the antenna. This is implemented by arranging a quarter wave resonator (420, GND) tied to the ground plane so that the short-circuited end of this resonator is close to the outer end of the radiator. The capability of the antenna at the frequencies below 1 GHz improves because of the more favourable distribution of the field of the ground plane.Type: ApplicationFiled: May 11, 2011Publication date: August 1, 2013Inventor: Heikki Korva
