You place two antennas 5.00 m apart, each broadcasting a 1632.0 MHz radio signal, in phase with each other and uniformly in all directions. (Radio waves move at the speed of light.) You then study the intensity at various points the same distance from the midpoint between the antennas, a distance that is very large relative to the separation between the antennas. Measuring angles from a reference line that passes through this midpoint and is perpendicular to a line segment...

A cell phone in a poor signal strength area is broadcasting a signal of freuquency 1.865 GHz with a power of 2.95 W. The signal is broadcast omnidirectionally. a) Determine the intensity of the signal at a distance of 1.25 km from the cell phone. b) Determine the intensity of the signal at a distance of 5.75 cm from the cell phone (inside the caller's head) Determine the rms magnitude of the electric field at a distance of 5.75 cm...

In an experiment to demonstrate interference, you connect two antennas to a single radio receiver. When the two antennas are adjacent to each other, the received signal is strong. You leave one antenna in place and move the other one directly away from the radio transmission tower. How far should the second antenna be moved in order to receive a minimum signal from a station that broadcasts at 95.4 MHz?

An astronomical radio telescope consists of two antennas
separated by a distance of 206 m. Both antennas are tuned to the
frequency of 24 MHz. The signals from each antenna are fed into a
common amplifier, but one signal first passes through a phase
selector that delays its phase by a chosen amount so that the
telescope can "look" in different directions. When the phase delay
is zero, plane radio waves that are incident vertically on the
antennas produce signals...

Problem 5 The configuration shown below depicts two vertically oriented half-wave dipole antennas pointed towards each other, with both positioned on 100-m-tall towers separated by a distance of 5 km. If the transmit antenna is driven by a 50-MHz current with amplitude Io 2 A, determine: Reflecied 100m (a) The power received by the receive antenna in the absence of the surface. (Assume both antennas to be lossless.) (b) The power received by the receive antenna after incorporating reflection by...
