Abstract:
Antennas contain numerous free electrons that can move in masses in accordance with an electrical charge. This mass movement of electrons creates an electrical current. Since the current is alternating in an antenna, the electrons move in unison back and forth around an average position. An antenna operating at 1.41 MHz is operating at 14.1 millions of cycles per minute. My mentorship incorporates basic antennas like the dipole as well as internal antennas. Internal antennas are capable of directing waves away from the brain. A team of scientists funded by Telstra investigated links between cell phones and cancer. In a study with 200 mice, half were exposed to GSM-type pulsed microwaves similar to those in cell phones, while the other half (the control group) were not. A significant increase in B-cell lymphomas was evident in the group subjected to the radiation. B-cell lymphomas are implicated in 85% of all cancers. By not exposing the brain to direct GSM-type pulsed microwaves, internal antennas lower the risk of cancer. This presentation will show different types of antennas, their purpose, their performance, and their risk factors.
