Transmitting antenna

  1. Mar 31, 2009 #1
    Hello, I got the following problem.

    1. Assuming that your cell-phone antenna acts like a monopole, how long should it be if the
    cell phone operates at a frequency of 1.8 GHz? (Note: 1 GHz = 1000 MHz =
    1,000,000,000 Hz.)




    2. λ= c/f



    f would 1/T, T being the Hz. But that would be 0,0000000001

    Then, c is always the same value, right? Which would be c = 2.99792458 × 108 [m/s].

    I can't get the result. It's supposed to be about 4 cm:confused:

    Hello XodoX! :smile:

    Convert c to cm/s :wink:
