Abstract

The present invention is a varying angle antenna design to be used with an electromagnetic radiation dissipation device that reduces exposure to undesirable electromagnetic radiation. The dissipation device uses a varying angle antenna to capture radiation from an active emission source, such as a cellular telephone when it is transmitting. 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. Additionally, near the center of the varying angle antenna, the microstrip segments are narrower than the microstrip segments near the ends of the antenna. In general, the meandering segments include varying angles, which maximizes the operation of the antenna for absorbing undesirable electromagnetic radiation from cellular telephones.
