Moment methods. Arrays: collinear, broadside, endfire. Array synthesis. Mutual coupling. Log-periodic and Yagi arrays. Radiation from apertures: the waveguide horn antenna, parabolic dish. Antenna ...

When you think of directional ham radio antennas, you probably think of a Yagi, cubical quad, or a log-periodic antenna ... that explains the design and math behind it. We’ve also seen arrays ...
