Abstract : This report describes the results of an analytical and experimental study to determine the feasibility of developing octave bandwidth, electrically small, low profile antennas in UHF and VHF bands from 20 to 1200 MHz. The combination of achieving both small size and octave bandwidths in the frequency range from 20-160 MHz presents the most difficult challenge. Antenna elements examined include loops, disk cones, conical monopoles, Goubau, and microstrip spiral antennas. Results presented include experimental data on disk-cones, a scaled conical monopole, and a scaled microstrip spiral antenna. More work remains to be done, especially in the 20-40 MHz band. However, it is projected that, with continued development efforts, the desired results can be achieved.
