The Designing Process of an Antenna
The designing of antenna starts by understanding the requirements of the transmission and a person requires knowing about frequency and the wavelength for the antenna’s signal prior to starting work on it. The subsequent important step is having a good understanding of the type of antenna which would cater to your application. However, some applications do need many antennas and it might create confusion for the beginners. Students hassle free ask us, “do my thesis for me on Antenna Design” because they know that we never copy contents from other sources and prepare assignments which are the result of extensive research on the topic.
The Length of an Antenna
The most modest antenna happens to be a solo piece of metal wire which is linked to radio. The majority of the modern transistor radios possess nearly a couple of antennas. Among them, one is a shiny and long telescopic rod which does pull out from a case plus rotates around to pick up FM signals. The second one is an antenna which remains inside the case and it remains secured to the chief circuit board which picks up the signals of AM.
Now, you may wonder why on earth you require a couple of antennas. Well, be known that the different wavebands’ signals get carried by various radio waves of dissimilar wavelength and frequency. Common AM radio signals possess a 1000 kHz frequency, while a common FM signal happens to be nearly 100 MHz. This is the reason they vibrate nearly a hundred times faster.
As all radio waves do travel at a similar speed which is 186,000 miles/second, AM signals possess wavelengths which happen to be one hundred times bigger compared to the signals of the FM. Hence, you require two antennas as a single antenna will fail in picking up such a vast range of wavelengths. This is the radio waves’ wavelength that you are attempting to detect which determines the type and size of the antenna which you require using.
The length of a rod-type antenna needs to be nearly half the radio waves’ wavelength when you are attempting to receive.
