The lock system can be seen as one of the critical points of the system because it has to ensure that the antenna will not open during launch, but also that it opens when in orbit, so an optimization of already existing lock systems is pursued.

For a receiving antenna, the open circuit voltage Voc stimulated by the incident electric field E ⇀ inc can be calculated by V oc = E ⇀ inc ⋅ l ⇀ eff (16).
A strong tunability of the antenna resonances via electrostatic bias is numerically demonstrated, opening perspectives to design tunable graphene-based nano-antennas.
For more than a dozen years, astronomers have been designing a unique new telescope: an oval-shaped ring of 40 antennas that would open up a little-explored part of the spectrum to "see" everything from extrasolar planets to the formation of galaxies.
Mr. Kleeblatt is always looking for new attitudes, approaches, techniques and imagery, or, as he put it, "My antennae are open".
Upon landing, he said, other antennas on the tipped spacecraft opened toward the earth, and three did not open at all.
During the 1995-2003 Galileo mission, the data return was constrained because the high gain antenna on the spacecraft didn't open correctly.
This may have been because the fourth solar panel may have partially opened and shielded the radio antenna.
The tag needs to get this DC power from an incoming RF signal whose polarity changes about 900 million times per second, and with the proviso that at a few meters from the reader, a small tag antenna provides an open-circuit voltage of only about 0.1 0.3 V.
