20080265038 | Antenna in Package with Reduced Electromagnetic Interaction with on Chip Elements - A IC package for a wireless device includes an antenna that is attached to the chip. The electrically conductive elements of the antenna are spaced away from the antenna and particularly the endpoint of the antenna to prevent interference with the antenna. An element on the IC package may be shielded antenna. The antenna may have the shape of a space-filling curve, including a Hilbert, box-counting or grid dimension curve. | 10-30-2008 |
20100109955 | WIRELESS DEVICE INCLUDING A MULTIBAND ANTENNA SYSTEM - A wireless handheld or portable device includes an antenna system operative in a first frequency region and a higher, second frequency region that includes an antenna structure, a matching and tuning system, and an external input/output port. The antenna structure includes at least one radiating element including a connection point, a ground plane layer including at least one connection point, and at least one internal input/output port. At least one radiating element of the antenna structure protrudes beyond the ground plane layer. The antenna structure features at any of its at least one internal input/output ports when disconnected from the matching and tuning system an input return loss curve having a minimum at a frequency outside the first frequency region of operation of the antenna system. The matching and tuning system provides impedance matching to the antenna system in the first and second regions of operation of the antenna system. | 05-06-2010 |

20140253407 | SLIM TRIPLE BAND ANTENNA ARRAY FOR CELLULAR BASE STATIONS - The present invention refers to a triple-band antenna array for cellular base stations operating at a first frequency band and at a second frequency band within a first frequency range, and also at a third frequency band within a second frequency range. Said triple-band antenna array comprises a first set of radiating elements operating at the first frequency band, a second set of radiating elements operating at the second frequency band, a third set of radiating elements operating at both the third and the first frequency bands, and a fourth set of radiating elements operating at both the third and the second frequency bands. The radiating elements are arranged in such a way that at least some of the radiating elements of the first set are interlaced with at least some of the radiating elements of the third set, and at least some of the radiating elements of the second set are interlaced with at least some of the radiating elements of said fourth set. Further the invention relates to a slim triple-band base station for mobile/cellular services that includes in its radiating part two or more of said triple-band antenna arrays. | 09-11-2014 |
