Question 6

When comparing a Yagi antenna and a patch antenna, which statement is generally true?

Accepted Answer

Yagi antennas typically provide higher gain and a more focused beam for longer-distance links compared to patch antennas.

Answer

Patch antennas offer higher gain and a narrower beamwidth than Yagi antennas.

Answer

Yagi antennas are omnidirectional, while patch antennas are directional.

Answer

Patch antennas are physically larger and more obtrusive than Yagi antennas.
