The possibilities for tunable electrically small antennas are explored and analyzed. Although experimental determinations were made of impedance characteristics from 30 to 220 MHz, the objective was to study the possibility of tuning and bandwidth control for antennas in the range 30 to 100 MHz. A considerable part of the discussion is devoted to acceptable circuit representations or models for the antennas. Both the electric monopole and the folded monopole, each over a conducting ground plane, are considered in detail. The practicality of having tunable small antennas is directly associated with the possibilities of remote tuning and remote bandwidth control. Both of these topics were investigated. The range required for the tuning unit was thoroughly explored and two examples are given of antennas which are properly tuned by an external tuning unit.
