In Part 1, we introduced the phased array concept, beam steering and array gain. In Part 2, we presented the concept of grating lobes and beam squint. In this section, we begin with a discussion of ...

An introduction to properties of individual antennas and arrays of antennas. Retarded potentials, dipoles of arbitrary length, radiation pattern, gain, directivity, radiation resistance. The loop ...

A method for calculating the vertical radiation pattern of a high-frequency curtain array erected on a flat hill or plateau is described; computations showing how this pattern depends on the steepness ...
