An investigation of broadband miniature antennas
NPS-52MV8091A.pdf (1.332Mb)Abstract
The report considers the application of a negative impedance converter to a short monopole antenna. The theory of short antennas and an analysis of the negative impedance converter are presented. The frequency- response characteristics of the negative impedance converter are analyzed. The performance of each of various miniature antenna configurations is compared experimentally with that of a 16 foot untuned whip antenna. The nonlinear behavior of the negative impedance converter is explored experimentally. Also considered is the manner in which atmospheric noise level influences the design of antennas intended to operate in the frequency region below the VHF band.
