Varying angle antenna for electromagnetic radiation dissipation device
A varying angle antenna design can be used with an electromagnetic radiation dissipation device to reduce exposure to electromagnetic radiation. The antenna captures radiation from an active emission source, such as a cellular telephone as it transmits. The device converts the captured radiation into an electric current and dissipates the collected current by spending it to operate a thermal, mechanical, or electrical device. The varying angle antenna is a printed circuit board trace antenna comprising a microstrip having several serially connected meandering segments. One or more meandering segments include 90-degree bends in the microstrip, and one or more meandering segments include bends of more and less than 90 degrees. Portions of the microstrip that are horizontally oriented are all parallel, while portions of the microstrip that are vertically oriented can be parallel or angled, depending on the bend angle. Near the center of the antenna, the microstrip segments are narrower.
