Abstract
Low profile array antennas for aircraft achieve improved performance with excitation circuits providing forced excitation of radiating elements to generate signals of desired relative phase and amplitude at the elements. Excitation circuits are structured for use of reactive turning for wideband operation. Monopole or slot array antennas, each including three or more radiating elements, can be grouped as antenna systems.
