(a) True

(b) False

I had been asked this question by my school teacher while I was bunking the class.

Query is from Principles topic in chapter Horn Antenna of Antennas

Answer 1

Right answer is (a) True

Explanation: Horn antenna uses Huygens principle where aperture field is considered as a second source which gives rise to far field. It states that each point on a primary wave front can be considered to be a new source of a secondary spherical wave and that a secondary wave front can be constructed as the envelop of these secondary spherical waves.
