Phased Array Definition:
Placing directive antennas in an array of like antennas and spaced so the individual antenna fields just overlap. This can be done with
Yagis, Helicals/Helix, Log Periodics and other directive antenna types like Patches, Cubical Quads and even Dipoles over a reflective
plane. Matching is easy for Yagis and narrow band antennas by combining, in phase and matching using 1/4 wave, 2, 4, 6 and 8 port
power combiners. Arrays of Helicals/Helix and Log Periodic broadband antennas requires special matching techniques.
