In this letter, a method of tunable gain microstrip antenna for compact pattern-reconfigurable array is proposed. The tunable gain element is realized by integrating a switchable resistive attenuator, ...
Space Kymeta’s new antenna promises ‘seamless’ satellite network ‘roaming’ "The ubiquitous user terminal that could interoperate across frequency bands and orbits was a key part of [the ...
Reconfigurable antenna ensures flexibility design, once it presents frequency agile and makes use of software defined and cognitive radios to cope with extendable and reconfigurable multiservice, ...
We propose a beamforming method based on curved conformal metasurfaces fed by a slot-coupled patch antenna array. This conformal metasurface comprises five distinct planar metasurface subarrays and ...
Gogo Galileo FDX antennas are produced at Hughes Network Systems’ Maryland facility. Credit: Bill Carey/AW&ST Hughes Network Systems has started shipping a second electronically steerable ...
Set up the antenna in the middle of the field, have it transmit some RF, and measure the signal strength at points along a series of radial lines away from it I’d end up with a spreadsheet, from ...
Using heat-activated nitinol metal, researchers have devised a reversible, shape-shifting, conical spiral antenna that needs no discrete external actuator. How a special nitinol compound and 3D ...
This letter proposes a broadband reconfigurable antenna capable of forming single and dual beam radiation, with switchable polarization states. The antenna consists of a reconfigurable power divider ...
2 Design and analysis of beam reconfigurable graphene-liquid antenna 2.1 Antenna design We design and numerically analyze the proposed graphene-based liquid antenna over mmWave frequency bands. The ...
Researchers from the UK and Ireland are developing a low loss active reconfigurable intelligent surface (RIS) for the next generation of indoor 6G antennas. 6G will include high frequency millimetre ...
