Homework 7
ECE 4370
Problem 1:
Assuming an ideal field distribution with uniform phase from the TE10 mode of a rectangular waveguide has been propagated to the aperture of a horn antenna with width A and height B, calculate the directivity pattern and ideal peak gain (assuming 100% radiation efficiency) in terms of A, B, and λ. (10 points)
Problem 2:
You must design a 4 GHz horn antenna with maximum peak gain, fed by a standard rectangular waveguide (a = 2b = λ/2). The maximum length of the flared horn antenna, Rp, must not exceed 50 cm. Provide an engineering diagram, fully dimensioned, for your company’s metal shop to produce. (10 points)
