Extremely Small Size Mechanical Antenna, Propagating Electromagnetic Wave

There are some challenges in effectively producing low frequency electromagnetic waves, such as the need of large scale antennas, particularly for submarine communications. Due to hardness and challenges of building low frequency antennas, some solutions are provided. Using acoustic wave is one of solution which is the most common alternative for low frequency electromagnetic waves. A new solution which is in the researching level, is known as Mechanical Antenna. This sort of antenna which enables us to propagate low frequency electromagnetic waves, has the advantage of being extremely small in comparison with common electrical antennas. Some efforts have been done on analyzing and testing this type of antenna in order to estimate the pattern and propagated power of mechanical antenna. In this paper, initially parameters affecting the power radiated in past researches has been investigated and a novel solution is provided in order to increase the propagated power.
