In Part 1, we introduced the phased array concept, beam steering, and array gain. In Part 2, we presented the concept of grating lobes and beam squint. In this section, we begin with a discussion of antenna sidelobes and the effect of tapering across an array. Tapering is simply the ...
This is the second article of our three-part series on phased array antenna patterns. In Part 1, we introduced the phased array steering concept and looked at the influencers on array gain. In Part 2, we’ll discuss grating lobes and beam squint. Grating lobes can be hard to visualize,...
If the 2D phased array is implemented on the ceiling with a height H to the ground and we use (θB,φB) the beam steering angle as soon as the phased array detecting the tag, the center coordinate of the phased array antenna readable region on the ground can be expressed as below. ...
