Satellite and Space Engineering - Problem #2
This is part of a series of problems looking at topics in satellite and space communications and systems engineering.
Determine the gain (in dBi) of a circular 'dish' antenna.
You are given the diameter of the antenna (in m), the frequency of operation (in Hz) and the antenna efficiency (as a %). Calculate the gain of the antenna (in dBi).
You should take the speed of light to be 299,792,458 m/s.
Hint: See <https://en.wikipedia.org/wiki/Parabolic_antenna#Gain> - but don't forget to convert to dBi!
Example: The gain of a typical direct-to-home 60cm TV receiving antenna at 12 GHz is around 36 dBi.
Some future problems in this series will build on work done in previous problems, so if you get a working solution I suggest you hang onto the code!

Can't get it to work for condition 1. Any tips? I get: 36.004213724092061, and it requires 36.004213724092068.
The test suite has been updated to test against a tolerance.
The third test is problematic --- importdata() fails when the .m file contains comments. There's probably better ways of checking that regexp() is not used.
