Q. antennas have gain less than reflector antennas but have more lenient tolerance on surfaces.
✅ Correct Answer: (B)
lens antennas
Explanation: lens antennas are complex in nature but are able to scale wider angles. in comparison to reflectors, their gain is 1 or 2 db less, but these have more lenient tolerance on surfaces. these have less rearward reflection, relatively low loss and can be easily shaped to the desired contours.
