6. A 10-GHz line-of-sight microwave communication link consists of two lossless parabolic dish antennas, each has 40 dB gain. If the receiver antenna requires 3 nW of receive power for good reception and the distance between the antennas is 35 km, how much power (in both mW and dBm) should be transmitted?

A vertical receiving dipole antenna at a position P is 15 km
away from a Hertzian dipole antenna that is also placed vertically
(see figure below). The receiving antenna measures an E field equal
to 10 mV/m.
(a) What is the value of E that the receiving antenna will
detect at a height of 3 km above P?

Exercise 35.4 Part A Constants Two radio antennas A and B radiate in phase. Antenna B is a distance of 120 m to the right of antenna A. Consider point Q along the extension of the line connecting the antennas, a horizontal distance of 40.0 m to the right of antenna B. The frequency, and hence the wavelength, of the emitted waves can be varied. What is the longest wavelength for which there will be destructive interference at point Q?...

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...

Two antennas are separated by 11.40 m and radiate in phase at
115 MHz. A receiver placed 185 m from both antennas measures an
intensity I0. The receiver is then moved so
that it is 1.45 m closer to one antenna than to the other. What is
the intensity measured by the receiver at its new position?
State your answer in terms of I0 and
round to 3 decimal places.
