TERIS TEST AND EVALUATION RANGE INTERNET SYSTEM

Shaver, John W. 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / TERIS is a CTEIP (Central Test and Evaluation Investment program) project to provide wideband communications facilities between major ranges and laboratories economically and reliably. TERIS uses existing modern technology, off-the-shelf hardware and software, and leased commercial telephone facilities, Nine ranges and two laboratory facilities have been surveyed to determine costs and feasibility of connecting the TERIS. An initial three-node network is planned to be operating in early 1994.

A planar dual-polarized phased array with broad bandwidth and quasi end-fire radiation for 5G mobile handsets

Ojaroudi Parchin, Naser, Zhang, J., Abd-Alhameed, Raed, Pedersen, G.F., Zhang, S. 11 April 2021 (has links)
Yes / A planar dual-polarized phased array is proposed for 5G cellular communications. The array has the properties of dual-polarization, wideband and quasi end-fire radiation, which is printed on one side of a single-layer substrate. The design contains two 8-element sub-arrays including horizontally polarized end-fire dipole antennas and vertically polarized end-fire periodic slot antennas, employed on the PCB ground plane of the 5G mobile platform. Both sub-arrays provide wide bandwidth to cover 28 and 38 GHz (promising 5G candidate bands). The -10 dB impedance bandwidth of the proposed CPW-fed dipole and slot antennas are 26.5-39.5 GHz and 27.1-45.5 GHz, respectively. Moreover, for -6 dB impedance bandwidth, these values could be more than 20 GHz (24.4-46.4 GHz for the dipole antenna) and 70 GHz (22.3-95 GHz for the slot antenna). The fundamental characteristics of the proposed dual-polarized 5G antenna array in terms of the impedance bandwidth, realized gain, polarization, radiation pattern, and beam steering are investigated and good results are obtained. The clearance of the proposed dual-polarized 5G antenna array is less than 4.5 mm which is sufficient for cellular applications. / This work is partially supported by the InnovationsFonden project of Reconfigurable Arrays for Next Generation Efficiency (RANGE), AAU Young Talent Program, and European Union’s Horizon 2020 research and innovation programme under grant agreement H2020-MSCA-ITN-2016SECRET-722424.
