Researcher and author: Dr. ( Afshin Rashid)
Note: It should be noted that Rectna has been studied in recent years, especially in the field of power transmission in the microwave band. For example, in theory, for a single frequency of 9.2 GHz, more than 10% efficiency is predicted .
Of course, the practical efficiency of making these devices may be slightly different and must be determined in practice. A dipole antenna with linear polarization and a length of 2 / λ, which has a relative bandwidth of 11%, will be able to collect about 75.2 pW . With regard to the low received power independent of each antenna, using an array of antibiotics in these cells is customary laws and its own procedures there.
One of the problems that has not yet been well solved in nanotechnology is how to establish an electrical connection between nano- electronic equipment and the macroscopic world without losing the capabilities of these nano-elements. One of these areas and new applications of nanotechnology are nano-antennas , which are used in various fields such as nanosensors, nano- communication networks , electricity generation and other similar topics and as one of the fields of the day. The development of nanotechnology are important. At nanoscale, graphene-based antennas are used to transmit EM waves . Graphene is a very thin single-atom plate of limited carbon atoms placed on a crystal lattice. اند. Due to the very low dimensions of nano-sensors, nano-antennas need a very high operating frequency to be usable . However, the use of graphene greatly helps to solve this problem. Due to the development of technology for manufacturing equipment in nano-dimensions, it is possible to make nano antennas and use them in various applications. Communication between nano-devices is a major challenge related to the development of nano-antennas and related electromagnetic receivers. Reducing the size of a traditional antenna to hundreds of nanometers leads to very high operating frequencies . At THz band frequencies, the very large bandwidth available leads to the loss of a much higher path than the lower frequency bands.
Conclusion :
It should be noted that Rectna has been studied in recent years, especially in the field of power transmission in the microwave band. For example, in theory, for a single frequency of 9.2 GHz, more than 10% efficiency is predicted .
