Abstract
We investigate nonuniformly-wound helical antennas without ground plane (antenna counterbalance is a wire pigtail), with aim to maximize RHCP gain. By optimizing radii and pitches of these antennas, we obtain antennas with the gain that is very close to the gain of the optimal uniformly-wound helical antennas with infinite ground plane, while the obtained nonuniform antennas are smaller and handier.
