Directional, high-gain antennas can be made using arrays of individual elements rather than through large horn or parabolic antennas. Individual radiating elements with controlled phase shift combine to create more gain in a desired direction. Initially arrays of dipoles, this technique matured in the slotted array antennas used in airborne radar systems, and form the conceptual foundation of the advanced AESA radars used in the latest generation of fighter jets.

This is the first part in a two video series on antenna arrays. When you’re finished with this video, go back to see Antenna Arrays Part 2. Come back next week to see part 2. We encourage you to pass this video along to your colleagues, friends, and your classroom. If you enjoyed this, we also invite you to also view Daniel Roger’s video, “Antenna Elements to Antenna Arrays.” If you have questions please email us.
