Claim Text:
1. An electrically small antenna system for radiation of a desired transmission signal, comprising: a conductive cylindrical shell having a circumference and a height; a ground plane electrically connected with the conductive cylindrical shell, the height of the conductive cylindrical shell aligned along an axis orthogonal to the ground plane; a cap of the conductive cylindrical shell coupled with the conductive cylindrical shell, the cap a distance distal from the ground plane equal to the height; a plurality of power amplifiers combined through a corresponding plurality of independent interior center conductors, the plurality of independent interior center conductors configured to inhibit transmission of at least one harmonic of a frequency of the desired transmission signal, each independent interior center conductor aligned with the axis orthogonal to the ground plane and centered within the circumference, each independent interior center conductor terminated at the cap; wherein the electrically small antenna system is configured for: receiving the desired transmission signal; transmitting the desired transmission signal through the conductive cylindrical shell to the ground plane via the plurality of independent interior center conductors and the cap; inhibiting radiation of a target harmonic of the frequency; and radiating the desired transmission signal via the conductive cylindrical shell, the radiating configured to radiate an azimuthally regular radiation pattern, the radiating further configured to present a desired inductive feed point impedance required of a power amplifier of the plurality of power amplifiers.
