The omni directional antenna is an antenna system that radiates power uniformly in all directions. The only 3 dimensional omni directional antenna is the isotropic antenna, a hypothetical construct derived from actual antenna radiation patterns and used as a suggestion for specifying antenna gain and radio system effective radiated power. Practical...
An antenna that is able to receive signals from many directions is called a multi directional antenna. There are many size and shapes of multi directional antennas. They have different features. There are mainly two types of multi directional antennas, one being the indoor antenna and the other being the outdoor antenna. The indoor antennas can be ...
Television antenna signals are strongest and reception is generally the best when the station's transmitting tower is in clear line of vision with the home receiving the broadcast. Mountains, buildings or trees that block this line of sight tend to weaken and degrade the received signal. The signal also becomes weaker as it travels further from the...
Basically an antenna is an aerial. It has the main function to transmit and receive the radio waves. It is an electronic device that converts the radio frequencies into electromagnetic waves and vice versa. Indoor antennas are the antennas used inside the home or any other such place. There are varieties of indoor antennas. All the electronic de...
Reception is a process of receiving electromagnetic signals through antennas. If the antenna is placed next to the transmitter then there would be a perfect reception of signals. But it is not possible for everyone to have his or her antenna next to the transmitter. There will be a proper reception of signals in the nighttime. This is because there...
Antennas are the electronic devices used to transmit and receive radio signals. They are the important and essential component for a home. The antennas are responsible for providing good and proper signals. There are many types of home antenna systems are available.
1. Normal antennas:
These are the antennas usually used to receive ra...
Antennas are the electronic devices that are used to transmit and receive radio signals. These are electrical conductors for radio waves. Heinrich hertz discovered antennas in 1888. He discovered the antennas to prove the existence of electromagnetic waves. They convert radio frequency electrical current to electromagnetic waves and vice versa. The...
The function of antennas at base stations of cellular radio systems has been proven to be a successful way to increase the performance and the channel ability of personal communication systems. In compare to those technically highly developed base station antennas, the exterior and the practical principle of car antennas with omni directional patte...
A cell phone is an electronic device that is portable for talking over long distances. Cell phone connects to the cellular network of the site of cell which is further connected to the telephone network of public. Mobile phone offers many services other then acting as a phone. It offer the services like SMS, access to internet and also the MMS faci...
Antennas are the electronic devices that are used for reception and transmission of radio waves. In other words it is an arrangement of aerial electronic conductors that are designed to receive and transmission of radio waves. Antennas convert radio frequency electric currents into electromagnetic waves. Antennas are used in all most all the electr...
