Introduction. 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 ...

An example of the elevation pattern for this antenna, in relative field, is shown in Fig. 9. Using the Fraunhofer equation, this array would have a radiating far field at 98 MHz of 1,088 feet. The ...

Advances are being made on the on-board systems of 21-GHz-band broadcasting satellite systems that can be used to expand Super Hi-Vision (SHV) broadcasting services.

From these base stations we see downward-facing spotlights, or “combination channels” of antennae radiation patterns. Each includes an array of frequencies targeting different users.
