All, I have a question regarding a horizontal transmit antenna over a ground plane. My questions implies a dipole. The questions:
What impact does the ground plane have on a horizontally transmitted signal? If the transmit antenna is 1 meter above the ground plane is the only signal received by a second antenna, say 10 meters away, the direct wave? This assumes no other reflecting surfaces within the area. If there is a reflected signal from the ground plane is does that signal incur a phase reversal? Under what conditions do phase reversals of a reflected signal occur? Finally, what is the angle of the direct wave (main lobe) from a horizontally polarized antenna? . And, assuming there is a second lobe at 1 meter, what angle would that second lobe be at, assuming horizontal polarity? Thanks for any info Regards, David Spencer ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
