Dependence on a small set of surface rovers for surface and atmospheric exploration exposes missions to higher than acceptable probabilities of failure. To mitigate this situation, we have developed enabling technology for small, low power, low cost sensors that can be scattered from multiple orbiters or secondary craft and form networks. Since antenna size is expected to determine wireless sensor...
An electrically small inductively loaded dual sector antenna is investigated by varying the geometrical relationships between individual antenna parameters. Bandwidth is increased by closely spacing the resonant frequencies of each stacked sector. Inductive copper strips across the antenna aperture are adjusted to shape each sector's resonant frequency response. Rigorous simulation of these geometrical...
