Question

(3) A radio transmitter array broadcasts on a frequency 10.525 MHz with two antennae 90 m apart (a) Find the angles of constructive interference greater than zero (see diagram). If you drive around (b) If one antenna is 180 degrees out of phase with the other (c) Make a graph of the intensity delivered as a function of angle. the antenna array in a circle, how many constructive interference maxima do you encounter? what now happens at zero degrees? You can do a little trig to get (x, y) points, but I suggest a ant. 1 polar plot. ant. 2
