A rooftop TV antenna is a great example of the type, called a Yagi-Uda array after its inventors. They set out to create a wireless energy transmission system using radio waves, and found ...

When you think of directional ham radio antennas, you probably think of a Yagi, cubical quad ... We’ve also seen arrays that require multiple elements driven out of phase to get similar effects.

Including loop antennas in an array or as part of Yagi configuration will further increase directivity. Omnidirectional antennas feature no design alterations to affect the direction of a signal.

Effects of the earth. Reciprocity, receiving antennas, effective length and area. Moment methods. Arrays: collinear, broadside, endfire. Array synthesis. Mutual coupling. Log-periodic and Yagi arrays.

including the isolated antenna, the two-element array, the circular array, curtain arrays, Yagi and log-periodic arrays, planar arrays and three-dimensional arrays. Coverage includes analysis of ...

Key aspects of the electromagnetic wave behavior and design of antennas and antenna arrays from wire dipoles and Yagi-Uda antennas above the Earth’s surface to aperture antennas such as horns and ...
