A Compact Multiband Integrated Microwave Antenna

A unique, compact, multipurpose antenna system capable of operating in three frequency bands is described. Design techniques and empirical data are presented. Illustrations and performance characteristics of each antenna and the composite assembly are given. The overall antenna system performance is very satisfactory. Each portion of the system shows high gain and good radiation pattern and voltage-standing-wave-ratio characteristics. Measured data presented show that the interaction between antennas due to their close proximity is minimal. Results indicate that the design concept is good and satisfies the demands of many sophisticated radar systems.
