Beam steering unit (BSU) is one of the important subsystems of Phased Array Radar [3], and is responsible for electronic steering of the beam. The BSU [1] has to interact with the Beam Scheduler for receiving the beam parameters like azimuth, elevation, frequency etc. Based on beam ...
In a microwave landing system the individual words of a train of command words generated by the antenna beam steering unit are applied to a polynomial generator where each is, seriatim, summed with a polynomial check word generated in a previous operation. The result is shifted once toward the...
BEAM EMITTING UNIT, FINE PROCESSING METHOD AND DEV 优质文献 相似文献Method and system for steering antenna beam A hybrid wireless network system is disclosed. The hybrid wireless network system includes an antenna array, an analog subsystem, and a digital subsystem. The antenna array at least inclu...
Our design does not use any mechanical elements, external light sources, or reflectarrays, creating, for the first time, a highly robust and fully-integrated beam-steering device solution. We demonstrate a proof-of-concept beam-steering metasurface optimized for operation at 100 GHz, offering ...
5e. In addition, as seen from our simulations, the width of both zero- and first-order diffracted beams is narrower when the total number of unit elements is larger (Supplementary Fig. 16b). Fig. 5 Tunable beam steering with MQW-based all-dielectric metasurface. a Photographic image of the...
Since Joule heating is used as the stimuli triggering insulator-to-metal tran- psirtoioonf-ionf-VcoOn2caenpdt the unit-cells have a relatively large thermal mass, the beam-steering speeds offered metasurface are limited to millisecond time-scales. However, it should be noted that by the much...
We adopt 8 × 8 unit cells to construct the whole transmitarray, and then place it above a horn antenna. The measured results show that the transmitarray-based horn antenna achieves beam steering with the scan range of ±60° ×±60° at 5.4 GHz, and this steering capability can be ...
intra-pulse beam steering and its mathematics model were researched,which could keep the swath width and reduce the antenna gain loss.Finally,the antenna gain losses with the two methods were compared through simulating results.The validity of the intra-pulse beam steering(IBS) was proved at last...
Of the two wired rubber belts, one is connected to a stalk via steering wheel and the other to the ballast with adjustable weight for balancing load during upper and lower stroke of motor. The said beam-pumping unit has good balancing effect, high efficiency and other advantage.白连平...
The concepts are validated with a compact device for 5G/4G/Wi-Fi 2.4/5/6E performing a beam steering in the 5G without disturbing the radiation patterns of the other bands. This device demonstrates that the functionalities of two metasurfaces may be exploited in a single design if the ...
