Radio antennas are the devices that are used to that send and receive radio signals. Radio waves cover only a small part of the electromagnetic spectrum, which is made up of waves with varying wavelengths. A radio antenna basically consists of long strips of aluminum that changes radio waves, traveling at light speed, into electricity, which is then used to manipulate the electromagnetic field. Radio waves are caught in the air and then filtered into the circuit box.
Radio waves are easy to generate, can travel long distances and can penetrate buildings easily, so they are widely used for communication, both indoors and outdoors. These waves also work in heavy wooden terrain, can cross glass walls and even work well in the moving vehicles.
There are few properties of radio waves which make it distinct and usable. The first consideration is frequency. The frequency of the wave is the number of the cycles of a sine wave completed in one second. In the case of moving waves, such as radio waves, the frequency can be thought as the number of cycles of the wave that pass a given point in one second. The term hertz was designated for use in lieu of the term cycles per second when referring to the frequency of radio waves.
The alpha state of mind begins at a tip of inner relaxation where the brain's frequencies are lowered into what is known as the alpha brain waves. When wandering from beta to alpha the human mind's frequencies begin to descend down to a range of about 9 to 14 cycles per second. The alpha brain waves allow for a state of tranquility and calmness. Alpha is the point in which the mind is most receptive to subconscious programming. The programming that can be done to the mind in alpha is pretty much identical to hypnosis but when harnessing meditation with the alpha brain waves one is able to use it to their advantage.

In early times messages were sent over the wires by alternately turning electrical currents on and off, producing a series of "dots" and "dashes" in accordance with a telegraph code. There were many drawbacks of this system like it was one to one message delivery method , and was wire dependent or we can say the media was the wires that had a network between the places where the communication was needed. Another was the data transferred in coded form, special training was needed to code and decode the data.
An electrical device designed to receive and transmit electromagnetic waves is called an antenna. Antennas are commonly used in radio, television broadcasting, cell phones, radar and other systems involving the use of electromagnetic waves.
