It is an electronic device used to transmit and receive radio signals. A directional antenna is an antenna that radiates greater power in one or more directions. This allows increased performances on transmit and receive and receive and reduced interference from unwanted sources. All the antennas are slightly directional. The normal antennas have a...
Being able to talk on a handheld gadget without wires crossways the world is really a great achievement in technology. Few people stop and imagine about this minor miracle. However, when someone stuck somewhere unable to make a call because of a poor cell signal, the appreciation for this technology can be tested. Regrettably, cellular service prov...
The elements of the antenna array means the collection of all the similar radiation and elements related to the antenna, where the counting of the elements starts from 1 till N number. The similarity of the elements is judged on the basis of the same frequency, which means to derive voltage of each element one has fixed amplitude and phase angle. T...
