Development of World’s Smallest TV Antenna
Television is considered as one of the most important media of communications in Mexico. Several tests conducted in cities like Tijuana, Guadalajara and Mexico City, demonstrated that oftentimes the challenge is the successful transmission of signals to some of the more remote areas, especially indoors.
Typically a Yagi array antenna is used for
TV reception. Yagi antenna provides a directed beam that goes towards the TV tower, permitting a high degree of signal reception. Dr. Tecpoyotl’s team developed an antenna that is miniaturized into a smaller footprint, while at the same time improving the signal stability, compared with other passive antennas.
Underwater environmental sensor networks require wireless communications that can be obtained using electromagnetic waves. Thus, antenna design is a key factor regarding the global performance of such underwater transmission systems. The study of seawater properties leads to comparing the conduction loss and dielectric loss of an electromagnetic wave. A simulation model of an original antenna design is proposed to optimize link budget underwater communication systems.
