根据第二段"A radio telescope is a device that typically uses a large dish antenna(抛物面天线)to collect the low-energy radiation emitted by objects in space." 射电望远镜是一种通常使用一个大的碟形天线来收集太空中物体发出的低能辐射的设备。可知射电望远镜能够捕捉到发射低能量...
[2], an 11.5-dBi broadside gain was achieved from a 2 2small patch array utilizing wirebond as the interconnection be-tween the die and the feed line of the off-chip antenna.Although chip-to-chip interconnections (e.g.,wirebond) show low inser-tion loss at mm-wave frequencies below ...
“position keeping” control measures to return it to the initial fixed position. The ITU stipulates that the orbital position retention accuracy of Ku-band broadcasting satellites should not be less than ± 0.1 degree, and the deviation of the antenna beam relative to its nominal pointing should...
wherein each set of DL RS resources is associated with a respective array partition scheme for an antenna array, and each DL RS resource in a set of DL RS resources is associated with a respective subarray of the antenna array partitioned based on the respective array partition scheme associat...
Various aspects of the present disclosure relate to methods and apparatuses for wireless communication with extremely large antenna arrays. Some implementations of the methods and apparatuses described herein may include a user equipment (UE) for wireless communication, comprising: at least one memory; ...
The methodology entails considering a scenario with a random uniform line-of-sight channel, where User Terminals (UTs) are uniformly distributed within the coverage area of the BS antenna array on the building facade. The system undergoes assessment with a focus on both ...
