The second radiator is connected to the heat sink and has a second open terminal and a second ground terminal. The second open terminal of the second radiator is coupled with the first radiator and excited to generate a second resonance mode, thus the dual band antenna is capable of receiving or sending and both a second band signal. | 2017-09-14 |
20170264017 | LENS BASED ANTENNA FOR SUPER HIGH CAPACITY WIRELESS COMMUNICATIONS SYSTEMS - An antenna includes a stack of cylindrical lenses combined with feed elements to provide multi-beam coverage for a given wireless communication sector. Each cylindrical lens disc has approximately the same height as the feed elements being used with the lens. To overcome the problem of interference from cables and opposing feeds, feed elements are placed around the lens. The cylindrical lenses are stacked such that a small gap exists between each pair of adjacent cylindrical lenses, allowing for cable lines to pass through between the pair of the cylindrical lenses, and thus removing interference for 360 degree coverage. Cable lines are arranged such that they only traverse the portion of the circumferential surfaces of the cylindrical lenses that do not interfere with the field of view of the RF signals generated by the corresponding feed elements. | 2017-09-14 |
20170264018 | RECONFIGURABLE MULTI-BAND ANTENNA WITH INDEPENDENT CONTROL - There is disclosed a multi-band reconfigurable antenna device having at least one radiating element. The radiating element is connected to a single port by way of at least first and second matching circuits arranged in parallel. A high pass filter is provided between the first matching circuit and the radiating element so as to allow passage of a first, higher frequency RF signal through the first matching circuit. A low pass filter is provided between the second matching circuit and the at least one radiating element so as to allow passage of a second, lower frequency RF signal through the second matching circuit. The high pass filter blocks passage of the second, lower frequency RF signal through the first matching circuit, and the low pass filter blocks passage of the first, higher frequency RF signal through the second matching circuit. The first and second matching circuits are adjustable independently of each other so as to allow the first and second RF signals to be tuned independently of each other. | 2017-09-14 |
20170264019 | MULTIBAND ANTENNA - An antenna comprising first and second radiating elements disposed in a collinear configuration on a dielectric substrate, wherein the first radiating element comprises a feed point. A first inter-element phasing section is conductively coupled to the first and second radiating elements, and has a meander line configuration adapted such that the first and second radiating elements radiate electro-magnetic radiation in-phase over a first range of frequencies. Third and fourth radiating elements are disposed in a collinear configuration on the substrate, and the third radiating element is electromagnetically coupled in parasitic relation to the first radiating element. A second inter-element phasing section is conductively coupled to the third and fourth radiating elements, and has a meander line configuration adapted such that the third and fourth radiating elements radiate electromagnetic radiation in-phase over a second range of frequencies which is different from the first range of frequencies. | 2017-09-14 |
20170264020 | SATELLITE GROUND TERMINAL UTILIZING FREQUENCY-SELECTIVE SURFACE SUBREFLECTOR - A device and method are described for duplex satellite communication over a single satellite antenna. A satellite ground terminal may utilize a frequency-selective surface module including a frequency-selective surface as a subreflector acting as a frequency diplexer to separate signals received and/or transmitted by a first feed and a second feed of a satellite ground terminal, where each feed has a separate antenna horn. The frequency-selective surface module may be used in combination with a second subreflector such that a first feed and a second feed of the satellite ground terminal are implemented on the same side of the frequency-selective surface module. | 2017-09-14 |
20170264021 | DIPOLE-SHAPED ANTENNA ELEMENT ARRANGEMENT - A dipole-shaped antenna element arrangement comprises two pairs of radiator halves which are arranged so as to be rotated by 90° to one another and are oriented in a radiator plane at a distance in front of a reflector and in parallel therewith. The radiator halves are arranged on a balancing and/or support arrangement. There is a passive beam-shaping frame which is arranged at a distance from the radiator halves towards the reflector. The passive beam-shaping frame has at the corners thereof a broadening of the peripheral frame web thereof, said broadening of the frame web extending in parallel with the radiator plane and/or transversely to the radiator plane. | 2017-09-14 |
