Abstract
The dual scan corner reflector antenna is a frequency scanned antenna for dar, direction finding, or guidance systems which provides increased information gathering capacity over that of prior art systems. The antenna utilizes a helix frequency scanning feed to drive a dipole antenna array. Each output port of the feed is connected to a power divider or combiner to form a common line to the antenna element. At each end of the helix frequency scanning feed are hybrid terminals used to simultaneously form two receive or transmit radiation patterns. The respective helix feed couplers have symmetrical values about the center of the helix feed, allowing the two radiation patterns to be mirror images of each other at the same frequencies. These two radiation patterns can be scanned simultaneously and independently.
