(a) Calculate the length of a quarter-wave monopole antenna for the center of the cellular radio band (860 MHz) and the center of the PCS band (1910 MHz).
(b) Assuming equal transmitter power applied to both of the above antennas, would there be any difference in the power density generated at a receiving antenna? Assume free-space propagation. Explain.
(c) If the above antennas are used as receiving antennas, which of the two would produce a stronger signal at the receiver input, and by how many decibels? Assume equal power density at the antenna. Explain.
