To answer your questions:

To answer your questions: <br />Mylar couldn't be used I believe (at least not instead of aluminum) because it's important to have a conducting surface that makes up the interior of the horn. <br /><br />Although there are other possibilities for building a good microwave antenna, the horn shape is special because it, as you suggest, helps to guide the signal to the feed. The gradual taper of the horn-shape provides what electrical engineers call an impedance match to free space. This allows the power incident on the horn to more efficiently reach the detector. <br /><br />Think about how a megaphone (shaped like a cone) allows us to amplify our voice-- the physics is very similar in both cases. In the case of the megaphone we deal with mechanical waves while in this case we deal with electromagnetic waves. The wikipedia article on horns is not bad if you want to know more: http://en.wikipedia.org/wiki/Horn_antenna<br /> <br />In short, yes a straight box-shape would be significantly less efficient.
