请问什么叫天线的视轴boresight?谢谢! 怎么没人回呀? 没有人回答是因为随便在网上一搜索就有答案的。下面是wikipedia的结果,我来当一下搬运工Antenna boresight In telecommunications and radar engineering, antenna boresight is the axis of maximum gain (maximum radiated power)) of a directional antenna. For ...
As the needs for high gain antennas for CubeSats begin to evolve, deployable reflector antennas have re-gained significant interest. A particular class of deployable reflectors known as umbrella reflectors have been considered for several CubeSat missions. The umbrella reflector surface consists of a ...
So, it is possible that the AR is very high, but there is no multipath component due to the low antenna gain for given direction. And if in general the antenna is lossy with low gain, the received signal strength will be small and therefore more prone to errors—even if the AR is ...
Based on the simulation results , a cobra antenna constituted by four reflectors is designed , the antenna produces a radiation pattern with a boresight peak , and the antenna gain reachs to 28 . 4db 通过数值仿真,设计了一种由四块反射面组成的cobra天线,天线在轴向上辐射场最强,...
Our analytical results indicate that the diversity gain for the zero boresight case is determined only by the ratio between the equivalent beamwidth at the receiver and the jitter standard deviation, while for the nonzero boresight case, the diversity gain is related to the ratio of the ...
In [6], the three commonly received diversity combining schemes such as the maximal ratio combining (MRC), the equal gain combining (EGC) and the selection combining (SC) were employed to improve the amount of harvested RF energy instead of the value of received signal-to-noise (SNR). ...
