SUPERDIRECTIVE ANTENNAS AT LOW FREQUENCIES

Abstract

A broadside superdirective antenna consisting of 5 sources was constructed in the 100 mc band. Though a superdirectivity factor of about 2 was obtained, no supergain appeared. Thus the feasibility of superdirectivity for low frequencies was proved, but its application is limited, because of the low energy efficiency. It is possible that for some application where space economy prevails efficiency considerations, and where only a narrow band is needed, for exampleALTIMETER ANTENNAS IN AIRCRAFTS, A SUPERDIRECTIVE ANTENNA CAN BE A SOLUTION.
