Application: Short monopole. A short monopole is used in a mobile telephone. The limitation is that a telephone of this type should not transmit more than 3 W. IT the telephone transmits at 76 MHz and the antenna length is 0.1 m:
(a) Calculate the required current in the antenna. Assume a perfect conductor for the antenna.
(b) What is the maximum range of the telephone if the amplitude of the electric field intensity at the receiving antenna should be no lower than 1 m V/m.
