Where are Smart phone Antenna? - Long Anteena VS Short Anteena.

Why You Need, To Read It?

     You have definitely see old mobiles with a large Antenna at the top, and those phones was very big in size and very heavy.
But,
     Now our phones are slim, light weight with amazing features.

• Is their any Antenna in our phone

     Answer is - YES

     In starting days of mobiles, its components are very big in size. Antenna technology of that time is very simple. So, Antennas of those phones are very big.
And it is impossible, to fix such a big Antenna inside the phones.
But,
     We know, By the time technology shrinks itself.
     Size of mobile phone components is reduced, and Antenna technology is also improved. So, size of  Antennas are also decrease.
And due smaller in size we are able to fix it inside our phone.

Different Antennas Length For Different devices:-

      You can see Antenna's, in those devices which can receive or transmit signals. ( Radio, Routers and phones etc.)
     Length of an Antenna is depends on, of which frequency of signals you want to receive or transmit.
     Length of an Antenna is between 1/2 and 1/4 of wavelength of any frequency.(When we increase frequency, wavelength will decreases)

     We use large Antennas in Radios because they receive low frequency signals. (High wavelength)
But,
     Mobile Antenna's are small in size (6-7 inches). Mobile phone works on high frequency.( Low wavelength)

     Now, you will definitely think that, why don't we see any Antenna in our phone. Generally size of our phones are 4-5 inches,  but size of Antenna is large (6-7 inches).

Where Is Antenna?

      If you have an stylish & slim phone. You will definitely find it ugly, when size of Antenna is larger then your phone.
So, we need to reduce Antenna size.
     Now, a new concept is come, which is Printed Antenna.

Printed Antenna :-

    Printed Antenna's are printed inside the phone with a metal strip in a zig-zag pattern.
    So,  they will take less space with the same length.

     Nokia introduced printed Antenna (1998-99). They implement this Antenna in their phone.

     Now, in modern phones, you can notice some cutouts on the body of the phones.(metallic body phones)

     In this concept your phone's back panel is act as an Antenna,  and all the things work smoothly.

    In upcoming 5G technology, frequency of signals will be increased and wavelength of signals decreases and size of Antenna will also decreases and then, we are able to reduce size of mobile phones.

   Now, you can imagine a stylish, latest phone with an Antenna. It look very ugly and it will be in-convenient to use.
So, by doing some improvements in technology, we don't have to face these big Antenna's .
Printed Antenna's works efficiently and smoothly.
