Abstract
The present disclosure is directed to a multi-ring switched parasitic array for improved antenna gain. The array includes multiple rings of parasitic elements configured around a central monopole element. Each parasitic element may be connected to a corresponding load circuit. Variable impedances may be applied to the parasitic elements via the variable impedance loads for causing the antenna array to produce a desired radiation pattern and/or for increasing gain of directional beams radiated by the parasitic antenna array.
