3. What is a folded dipole antenna?
a) A type of ground-plane antenna
b) A dipole configured to provide forward gain
c) A dipole constructed from one wavelength of wire forming a very thin loop
d) A dipole one-quarter wavelength long
For the given quarter wave dipole antenna, if the radiation resistance is 50 ohms and the loss resistance is 20 ohm, then estimate the radiation efficiency.
A 1-m long dipole antenna is driven by a 150 MHz source having a source resistance of 50 ohms and a voltage of 100 V. If the ohmic resistance of the antennas is given by RL = 0.625 ohms, find the:(a) Current going into the antenna (Iant)(b) Power dissipated by the antenna(c) Power radiated by the antenna(d) Radiation efficiency of the antenna
